Europe Weather by Month: A Data-Led Guide

The first time I tried to plan a European trip by month, I did what most people do: I looked up “average temperature in Europe” and got a single number. That number is useless. On any given day in July, Reykjavik and Athens are nineteen degrees apart, and one of them is having a heatwave while the other is drizzling at 13°C.

So this is Europe weather by month, done properly: real temperature, rainfall, sunshine and sea figures for thirty-five cities across five climate zones, month by month, with the dates that matter for tulips, lavender, snow, autumn colour and the midnight sun. Every number below comes with a source, and where I could not source something I say so.

Europe is five climates, not one

Almost every guide to Europe weather by month splits the continent into “north” and “south”, which puts Reykjavik and Rome in a two-bucket system and tells you nothing. Five zones is the minimum that works:

• Northern and Nordic. Iceland, Norway, Sweden, Denmark, Finland. Mild-ish coasts, brutal daylight swings, and a summer that is short but often lovely. Reykjavik’s warmest month, July, tops out at an average daily high of 14.9°C.
• Western and Atlantic. Ireland, Britain, France’s north, the Low Countries. Small temperature range, rain in every month, grey winters. Across the four benchmark months below, London runs from a 3°C January night to a 23°C July afternoon and no further.
• Central and Alpine. Germany, Austria, Switzerland, Czechia, northern Italy. Proper continental swings: Prague goes from a January high of 0°C to a July high of 23°C, and the mountains do their own thing on top of that.
• Southern and Mediterranean. Portugal, Spain, southern France, Italy, Greece, Malta, coastal Croatia. Bone dry in summer, surprisingly wet in autumn, and mild rather than warm in winter.
• Eastern. Poland, Hungary, Romania, the Balkans, Turkey. Colder winters and hotter summers than the west at the same latitude. Bucharest swings from a January low of -6°C to a July high of 29°C.

Keep those five in your head and the rest of this article makes sense. If you want the shorter strategic version rather than the data, my guide to the best time to visit Europe covers the same ground at a higher altitude.

All twelve months of Europe weather by month at a glance

Start here. This is my own verdict on each month, with the single figure I think should decide it for you.

Month	Best for	Worst for	Crowd level	One number that decides it
January	Northern lights, ski, cheap city breaks	Beach, long sightseeing days	Lowest	Glasgow gets 38 hours of sunshine all month
February	Carnival, Alpine snow, almond blossom	Anywhere you need daylight after 17:00	Low, except ski half-term	Tromso’s coldest month averages -3.2°C
March	Spring cities, late-season skiing, tulip gardens opening	Swimming, Alpine hiking	Low	Keukenhof opens 18 March in 2027
April	Blossom, gardens, Mediterranean cities before the heat	Sea swimming, high Alpine passes	Rising, Easter spikes	Sea temperatures are still 14 to 16°C
May	Almost everything except beach	Peak-season budgets	Moderate	Athens averages 25.2°C and 15.9°C in May
June	Long days, lavender, first swimmable sea	Value	High	June 2026 was western Europe’s hottest June on record
July	Northern Europe, the Alps, high latitudes	Southern city sightseeing at midday	Peak	Athens gets 364 hours of sunshine, Glasgow 149
August	Warmest sea of the year, Scandinavia, the Baltics	Southern Europe on a budget	Absolute peak	Croatia records 41.1 times more nights in August than January
September	Islands, cities, wine harvests, Finnish autumn colour	Nothing much	Falling	The Med is still 22 to 24°C
October	Autumn colour, cities, shoulder-season prices	The Riviera and the Bay of Naples	Low	Rome’s 107 mm of October rain is five times its July total
November	Value, Christmas markets from late month, museums	Daylight, coastal Croatia	Lowest	Dubrovnik’s wettest month, 145 mm
December	Christmas markets, Alpine snow, Arctic darkness	Long days anywhere north of Rome	Spikes 20 Dec to 2 Jan	Stockholm gets 6 hours 4 minutes of daylight on 21 December

The temperature table: 35 cities, four benchmark months

January, April, July and October are the four months that tell you the shape of a climate: deep winter, mid-spring, peak summer, mid-autumn. If you know those four for a city, you can interpolate the rest without much error.

Istanbul	Eastern	9°C / 4°C	17°C / 9°C	29°C / 20°C	20°C / 14°C

A few things jump out of that table that no month-by-month guide I read bothered to mention. Lisbon’s January high of 15°C is warmer than London’s April high. Milan in July (29°C) is hotter than Barcelona (28°C), which upends most people’s mental map of Italy and Spain. And Helsinki’s July high of 23°C is identical to London’s, which is why “Scandinavia is cold” is a statement about January, not about summer.

Rain: the number that ruins more trips than temperature

Temperature you can dress for. Rain you cannot. And the pattern of European rainfall is counter-intuitive in ways that catch people out every year: the Mediterranean is at its wettest in autumn, not winter, and Alpine cities are at their wettest in high summer, because that is when the thunderstorms build.

City	January	April	July	October	Wettest of the four
Amsterdam	67 mm / 12 days	41 mm / 9 days	77 mm / 10 days	90 mm / 13 days	October
Athens	48 mm / 5 days	26 mm / 4 days	5 mm / 1 days	48 mm / 4 days	January and October

Rome	70 mm / 8 days	76 mm / 9 days	21 mm / 2 days	107 mm / 8 days	October
Stockholm	39 mm / 10 days	30 mm / 7 days	72 mm / 10 days	50 mm / 9 days	July
Vienna	38 mm / 7 days	45 mm / 8 days	70 mm / 9 days	38 mm / 6 days	July

Zurich	65 mm / 10 days	74 mm / 10 days	115 mm / 11 days	87 mm / 10 days	July

Three findings worth carrying with you. Munich in July gets 132 mm of rain across twelve wet days, nearly three times its January total of 48 mm. Beer garden weather, yes, but soaked beer garden weather. Nice gets 12 mm in July and 133 mm in October, an eleven-fold jump, and worth knowing before you book a cheap late-autumn week on the Riviera. And Brussels has 19 wet days in January, the highest count in the table, which is more about persistent drizzle than volume: 76 mm spread thin.

The wettest place most travellers will meet is Bergen, on Norway’s west coast, where the wettest month is December at roughly 269 mm and even the driest month, May, still gets about 127 mm. Pack for it or route around it; my Scandinavia travel guide has more on the fjord coast’s habits.

Sunshine hours: the stat most weather guides skip

Two cities can share a temperature and feel completely different because one of them has twice the sunshine. This is the table I most wanted when I was planning winter trips in my twenties and never found.

City	January	April	July	October	July as a multiple of January
Marseille	145 h	244 h	369 h	187 h	2.5x
Valletta	158 h	246 h	366 h	220 h	2.3x
Athens	129 h	230 h	364 h	208 h	2.8x
Madrid	148 h	231 h	359 h	198 h	2.4x
Lisbon	144 h	235 h	352 h	213 h	2.4x
Nice	158 h	224 h	348 h	187 h	2.2x
Naples	115 h	189 h	313 h	189 h	2.7x
Barcelona	149 h	220 h	310 h	180 h	2.1x
Helsinki	38 h	196 h	291 h	84 h	7.7x
Bucharest	71 h	185 h	289 h	177 h	4.1x
Istanbul	71 h	159 h	285 h	140 h	4.0x

Munich	61 h	157 h	237 h	129 h	3.9x
Zurich	48 h	159 h	230 h	93 h	4.8x
Prague	50 h	168 h	226 h	121 h	4.5x
Berlin	45 h	158 h	218 h	111 h	4.8x
Amsterdam	63 h	183 h	217 h	109 h	3.4x
Paris	62 h	166 h	212 h	118 h	3.4x
Brussels	59 h	159 h	201 h	113 h	3.4x
London	45 h	148 h	177 h	105 h	3.9x
Reykjavik	27 h	140 h	171 h	83 h	6.3x
Dublin	59 h	159 h	164 h	102 h	2.8x
Glasgow	38 h	128 h	149 h	80 h	3.9x

Look at what happens in January. Marseille gets 145 hours of bright sunshine; Glasgow gets 38. That is a factor of nearly four, and it explains why a 6°C day in Provence feels like a treat and a 6°C day in Scotland feels like a punishment. In July the absolute gap more than doubles, to 220 hours, while the ratio narrows to 2.5: Marseille 369 hours, Glasgow 149.

The right-hand column is the seasonality of light. Reykjavik’s July is 6.3 times sunnier than its January, and London’s is 3.9 times. Valletta’s is only 2.3 times, because Malta is sunny all year. If you struggle with dark winters, that ratio matters more than the temperature column.

Sea temperature: when the Mediterranean is actually swimmable

Sea temperature is the number that decides a beach trip, and it is the one most weather summaries leave out. The air can be 26°C in May and the water still 17°C, which makes for a very short swim.

Sea	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
Barcelona	13.4	13	13.2	14.8	17.7	21.4	23.3	24.4	23.4	21.2	17.9	15.2
Nice	13.4	13.1	13.4	14.7	18.1	22	23.4	23.7	22.3	19.6	17.4	14.9
Athens (Saronic Gulf)	16	15	15	16	18.5	22	24	25	24	22	19.5	17
Dubrovnik (Adriatic)	14	14	14	15	18	22	24.5	25	23.5	20.5	17.5	15.5

The pattern is consistent across the whole Mediterranean, and it is not symmetrical around the summer peak. All four of these seas reach 22°C or within a whisker of it in June, peak in August, and are still above 19°C in October. October water is roughly as warm as June water, on beaches that have emptied out since August. Barcelona sits at 21.2°C in October against 21.4°C in June, which is a tie in any practical sense. Athens holds 22°C, Dubrovnik 20.5°C, Nice 19.6°C. Only Nice is properly bracing.

Water lags air by roughly two months, which is the whole explanation. It also means June, the month everyone books for a beach holiday, has the coolest water of the summer. Climates to Travel calls the Athens sea in June “a bit cool” at around 22°C and only rates July to September as properly warm.

North of the Med, the honest answer is no. Reykjavik’s sea runs from 5°C in March to 10.5°C in August. Tromso’s runs 4.5°C to 11.5°C. People do swim in both. They wear neoprene. For where the water is worth the trip, see my guide to the best beaches in Europe.

Daylight: the variable that changes a city break more than weather

A December afternoon in Stockholm ends at about half past two. That is not a weather problem, it is a scheduling problem, and it will halve the number of things you see.

Stockholm’s longest day in 2026 runs 18 hours 37 minutes, from a 03:31 sunrise to a 22:07 sunset. Its shortest is 6 hours 4 minutes. That is a swing of 12 hours 33 minutes across the year. Athens swings from 14 hours 50 minutes in June to 9 hours 35 minutes in December, a range of about 5 hours 15 minutes, which is less than half of Stockholm’s.

Further north it stops being a range and becomes an on-off switch. In Tromso, at 69°N, the sun does not rise at all from 28 November to 14 January, and does not set at all from 19 May to 26 July. Between 12 April and 1 September it never gets fully dark. Reykjavik, at 64°09’N, is gentler: on 21 December the sun comes up around 11:20 and is gone by 15:30, giving a December average of 4 hours 25 minutes, while on 21 June it rises at 02:55 and sets three minutes after midnight.

The practical rule: from November to February, every hour of daylight north of the Alps is a resource you have to budget. Open at nine, close at four, and plan indoor things for the dark end of the day.

Europe month by month, January to June

January in Europe

January is the coldest month almost everywhere in Europe, and the emptiest. Warsaw runs -1°C by day and -6°C at night; Oslo -2°C and -7°C; Helsinki -2°C and -8°C. Prague’s daytime high is exactly 0°C. Meanwhile Lisbon is at 15°C, Valletta and Palermo at 15°C, Athens at 14°C, and none of them are warm enough to sit outside comfortably after dark.

Light is the real constraint. Glasgow gets 38 hours of sunshine in the whole of January, Reykjavik 27, Helsinki 38. Athens gets 129 and Nice 158. If January is your only window and you need daylight, go south; if you want the aurora, go north and accept that you will be doing it in the dark, which is rather the point.

What January is best at: skiing between the Christmas peak and the February half-term peak, which is the cheapest good-snow week of the season; northern lights in Arctic Norway, Iceland and Finnish Lapland; and city breaks at their lowest prices of the year. Across the EU as a whole, August records 3.6 times as many overnight stays as January. That gap is your discount.

Watch out for: museum and restaurant closures in Mediterranean resort towns, which shut properly in January; and Alpine valley fog, which can sit below the ski resorts for days.

February in Europe

Statistically the coldest month in the far north. Tromso’s coldest month is February, with a monthly mean of -3.2°C, and Kraków’s January mean of -1.6°C only nudges up. But February has one thing January does not: the light is back. The Tromso polar night ends on 14 January, so by February you get proper blue-hour afternoons over the snow, which is the best possible backdrop for the aurora.

Southern Europe starts to signal. Mallorca’s almond blossom runs late January through February across roughly seven million trees, and mid-February is usually the best single week. Venice Carnival lands in February most years and is the one time a northern Italian winter city is busier than its summer self.

The catch is half-term. UK, French and Dutch school holidays cluster through February and Alpine lift-pass prices and chalet rates spike with them. If you can ski in the third week of January instead, do.

March in Europe

Meteorological spring starts on 1 March, which the weather does not care about. March is two different months depending on where you stand: Athens is already at 16.5°C by day, while Prague and Munich are still at single-digit highs and the Alps are having their best snow of the season.

Two dates to know. Keukenhof, the Dutch bulb garden that is the reason people come to the Netherlands in spring, opens 18 March in 2027 and runs to 9 May, with tickets on sale from mid-October 2026. And the clocks go forward on the last Sunday in March, which adds an hour of usable evening overnight.

March is my pick for southern European cities. Seville, Rome, Athens and Lisbon are all warm enough to walk all day and cool enough that walking all day is pleasant, and the crowds have not arrived. See visiting Europe in spring for the longer version.

April in Europe

April is the most photogenic month in Europe and the least reliable. It is when the continent’s flowering calendar peaks: Keukenhof’s tulips hit their best roughly 10 to 30 April, with the absolute peak between 13 and 25 April. Bonn’s cherry blossom on Heerstrasse peaked around 1 to 12 April in 2026 and lasts ten to fourteen days. Copenhagen’s Sakura Festival at Langelinie ran 18 to 19 April in 2026.

Temperatures are moderate everywhere and extreme nowhere: Rome 19°C, Barcelona 18°C, Paris 16°C, Berlin 13°C, Stockholm 9°C. What April does not have is warm water. The Mediterranean is 14.7°C at Nice, 14.8°C at Barcelona, 15°C in the Adriatic. Anyone selling you an April beach holiday in Europe is selling you a beach walk.

Easter is the wildcard. It moves, it spikes prices and crowds wherever it lands, and it closes things in Catholic countries on Good Friday and Easter Monday. Easter Sunday falls on 28 March in 2027 and 16 April in 2028, so in 2027 the Easter weekend and the clock change collide on the same night.

May in Europe

If you made me pick one month for a first trip to Europe, it would be May. Athens averages 25.2°C by day and 15.9°C at night, Dubrovnik 22.8°C and 16.4°C, Rome and Barcelona are comfortable, Paris and Berlin are at their best, and the Alps are green to about 2,000 m. Days are long, prices are below peak, and the heat has not arrived.

The one thing May cannot give you is swimming. Sea temperatures sit at 17.7°C in Barcelona, 18.1°C at Nice, 18°C in the Adriatic. Bracing at best.

May has also become the month when the summer heat starts early. Copernicus recorded four heatwaves in western Europe in 2026, and the first of them was in May. Treat May as reliably pleasant rather than guaranteed mild.

June in Europe

June brings the longest days of the year and the start of the real season. On 21 June, Stockholm gets 18 hours 37 minutes of daylight, sunrise at 03:31 and sunset at 22:07. Reykjavik averages 20 hours 55 minutes across the whole month. Tromso’s midnight sun runs from 19 May to 26 July, so June is entirely inside it.

Southern Europe crosses into summer proper: Athens 30.3°C by day, Dubrovnik 26.9°C, Palermo 27°C. The sea finally becomes swimmable, reaching 21.4°C at Barcelona, 22.0°C at Nice, around 22°C in the Aegean and Adriatic.

Provence’s lavender starts flowering on the Valensole plateau in mid-June and holds for about a month, with the strongest colour from late June into the first fortnight of July. Book that trip for the last week of June and you will usually be right.

The warning attached to June is new and it is serious. June 2026 was the warmest June ever recorded in western Europe, averaging 20.74°C, which is 3.06°C above the 1991 to 2020 norm and ahead of the record set only a year earlier in June 2025. Across Europe as a whole June 2026 averaged 19.14°C, 1.78°C above normal and second only to June 2019. June is no longer a safely mild month in the south.

Europe month by month, July to December

July in Europe

Peak everything. July is the hottest month across most of the continent, one of the two busiest, and the one where the gap between “north” and “south” becomes a genuine decision rather than a preference.

The southern numbers: Athens 33.2°C by day and 23.4°C at night, Rome 32°C, Madrid 31°C, Valletta 31°C, Palermo and Marseille 30°C. Sunshine peaks too: Marseille 369 hours, Valletta 366, Athens 364. Glasgow, at the other end, gets 149.

Rain is not evenly distributed. Athens gets 5 mm across a single wet day in July and Lisbon 6 mm. Munich gets 132 mm over twelve days and Zurich 115 mm, because Alpine July is thunderstorm season. If you are hiking in the Alps in July, the afternoon storm is the thing you plan around, not the temperature.

Provence’s lavender harvest usually begins around 15 July, and in a hot dry year some Valensole fields are cut by about 25 July. Aim for the first ten days of the month if the fields are the reason you are going. The Sault plateau, higher up, runs July into August.

July is also when Europe’s heat has started to break things. In 2026 the Acropolis closed to visitors from noon to 17:00 on the worst afternoons of the 21 to 23 July heatwave, and Greece banned outdoor labour between 13:00 and 17:00 in Attica and other badly hit regions. The same closure happened 22 to 25 July in 2025. Barcelona hit 40.7°C at the Fabra Observatory on 8 July 2026, its highest reading in more than a century of records.

August in Europe

August gives you the warmest sea of the year and the worst value of the year. August water: 24.4°C at Barcelona, 23.7°C at Nice, 25°C in both the Aegean and the Adriatic. Air temperatures roughly match July, with Athens at 33.4°C and Palermo at 31°C. Palermo records 46 days a year at or above 30°C and 19 of them fall in August.

The crowd figures are worth stating plainly, because they are worse than most people assume. Across the EU in 2025, 31.1% of all tourist overnight stays fell in July and August, and in every single EU country those were the two busiest months. Croatia concentrated 54.5% of its nights in those two months, Bulgaria 43.4%, Greece 41.6%. Croatia’s August was 41.1 times busier than its January.

The countries that spread their season best were Malta at 21.9%, Germany at 24.0% and Finland at 24.1%, which is a good clue about where to go in August if you must travel then.

My advice for August is the inversion: go north. Stockholm, Copenhagen, Helsinki, the Baltic capitals, Scotland and the Norwegian coast are at their annual best in August, and Tromso’s warmest month, July, still has a monthly mean of only 12.5°C, so the Arctic in August is pleasant rather than hot. Heading to Scandinavia and the Nordics in August is the single easiest way to travel in peak season without feeling it.

September in Europe

The month experienced travellers book. The Mediterranean sea is still 23.4°C at Barcelona, 24°C in the Aegean, 23.5°C in the Adriatic. Athens is at 28.9°C by day, Dubrovnik 26.2°C, Palermo 28°C. Air temperatures have dropped just enough to make cities walkable again, and the school-holiday crowd has gone home.

Northern Europe has its own September event. In Finnish Lapland, ruska, the autumn colour, peaks on average in the second week of September and lasts about ten days, then moves south at roughly 500 km every couple of weeks, reaching central and southern Finland in late September and early October.

The one thing to watch is that Mediterranean autumn rain begins. Dubrovnik goes from 30 mm in July to 130 mm by October. It is still mostly sunny in September; it just is not bone dry any more.

October in Europe

October is the best-value month whose weather still works, and a trap if you pick the wrong coast. Athens still averages 23.8°C by day with a 22°C sea. Palermo 24°C, Lisbon 22°C, Barcelona 22°C, Rome 22°C. That is short-sleeve weather with October prices.

The trap is rain. October is the wettest of the four benchmark months for a long list of places: Nice at 133 mm, Naples 136 mm, Glasgow 129 mm, Dubrovnik 130 mm, Milan 122 mm, Rome 107 mm, Barcelona 91 mm, Amsterdam 90 mm. The Tyrrhenian and Ligurian coasts in particular flip from the driest place in Europe to one of the wettest inside eight weeks.

Clocks go back on the last Sunday in October, 25 October in 2026 and 31 October in 2027, which takes an hour off your afternoon at exactly the point in the year you notice it most. Travel-industry data suggests everyone is catching on: European Travel Commission figures for late 2025 put revenue passenger kilometre growth at 6.7% in October and 7.1% in November, ahead of 4.4% in July.

November in Europe

Objectively the worst weather month in Europe and, for some trips, the best month to travel. It is dark, it is wet, and it is cheap. November is Dubrovnik’s wettest month of the year, wetter even than its 130 mm October. In the Arctic, the Tromso polar night begins on the 28th. Most of northern Europe is running four to six hours of usable light.

What November has: empty museums, cheap flights, and the start of the Christmas market season, most of which open in the last ten days of the month. Val Thorens opens for the 2026/27 ski season on 21 November 2026, with its La Grande Premiere weekend on 21 and 22 November, and runs to 2 May 2027.

If the point of your trip is indoors, November is unbeatable value. If the point is anything outdoors below the snowline, pick another month. My cheapest time to visit Europe guide goes into the pricing in more detail.

December in Europe

Two Decembers exist in Europe and they have almost nothing in common. There is the Christmas market December, roughly 25 November to 24 December, when Vienna, Nuremberg, Dresden, Strasbourg, Prague, Budapest, Tallinn and Colmar are the best versions of themselves and hotel prices reflect it. Then there is the 25 December to 2 January December, when prices spike again for a different reason and half of Europe is closed.

Light is the defining fact. Stockholm gets 6 hours 4 minutes of daylight on 21 December. Reykjavik averages 4 hours 25 minutes across the month, with the sun up around 11:20 and gone by 15:30 on the solstice. Tromso gets none at all. Athens, by contrast, still manages 9 hours 35 minutes.

December is the wettest month of the year in both Bergen, at roughly 269 mm, and Reykjavik. December in the Alps is snow rather than rain above about 1,500 m, which is why the ski season is properly open by mid-month. For where to go, my guide to European Christmas markets and to skiing in Europe both cover December in depth.

The five extremes, all twelve months

The four-month benchmark table is good for planning but it hides the shape of the year. Here are five places that between them define the outer edges of the European climate, with every month filled in.

Place	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
Reykjavik, Iceland	3.4/-2.2	3.4/-2.4	4.2/-1.8	7/0.8	10.1/3.8	13.1/7.1	14.9/9.1	14.2/8.6	11.5/6	7.7/2.3	4.9/-0.5	3.6/-2
Tromso, Norway	-0.4/-5.4	-0.7/-5.7	0.7/-4.4	3.9/-1.5	8.6/2.7	12.4/6.6	15.6/9.3	14.5/8.5	10.7/5.2	5.5/0.9	2.5/-2.1	0.9/-4
Palermo, Sicily	15/9	15/9	16/10	19/11	23/15	27/19	30/22	31/23	28/20	24/17	19/13	16/10
Dubrovnik, Croatia	12.6/7	13/7.1	15.2/9.2	18.2/12.1	22.8/16.4	26.9/20.3	29.7/22.6	30.1/23.1	26.2/19.2	21.9/15.5	17.5/11.7	13.8/8.1
Athens, Greece	13.3/6.6	14.1/6.8	16.5/8.6	20.2/11.5	25.2/15.9	30.3/20.5	33.2/23.4	33.4/23.6	28.9/20	23.8/15.9	18.8/11.9	14.7/8.5

Reykjavik’s whole annual range, from a 3.4°C winter high to a 14.9°C July high, is 11.5 degrees. Athens moves 20.1 degrees between its January and August highs. Tromso has average daily highs below freezing in January and February, and then reaches 15.6°C in July, warmer than Reykjavik ever gets despite sitting five and a half degrees of latitude further north; that is the warm Atlantic current running up the Norwegian coast.

Heat is now a planning variable, not a footnote

It is tempting to treat European summer heat as a matter of packing sunscreen. The last four summers say otherwise, and the figures below are all from primary sources.

• 48.8°C at Siracusa (Syracuse), Sicily, on 11 August 2021 is the highest temperature ever recorded in continental Europe, verified by the World Meteorological Organization. It broke a record of 48.0°C set at Athens and Elefsina on 10 July 1977 that had stood for 44 years.
• 47.8°C at Siracusa again, on 24 July 2023, during the Cerberus heat event that began on 10 July that year.
• 46.8°C at Agios Vasileios, Cyprus, in July 2024.
• 46.6°C at Mora, Portugal, on 29 June 2025, a provisional national June record, alongside 46°C at El Granado in Spain, a Spanish June record per AEMET.
• June 2026 was western Europe’s hottest June on record at 20.74°C, 3.06°C above the 1991 to 2020 average. June and July 2026 together, at 21.62°C and 2.79°C above average, were the hottest such period on record, beating 2022.

The knock-on effects are real and they are seasonal. The Acropolis closed at midday during heat spells in 2024, 2025 and 2026, typically 12:00 to 17:00 in July and August. Greece has repeatedly banned outdoor work between 13:00 and 17:00 during heatwaves. Our guide to Greek weather month by month breaks the country into five regions, because Crete, the Cyclades and Thessaloniki behave very differently. Wildfire risk peaks from mid-July to mid-August in Greece, and 2026 was an exceptional year across the west: EFFIS data put EU burnt area at 568,415 hectares from 1,647 fires by 13 August 2026, against a 20-year average of 197,347 hectares by early August. France set a modern record for area burned and Spain had one of its worst seasons on record.

None of that means avoid southern Europe in summer. It means: book accommodation with air conditioning, do your sightseeing before 11:00, treat 13:00 to 17:00 as siesta whether or not the country does, and have an indoor plan. My visiting Europe in summer guide has the full heat playbook.

One asymmetry worth noting from the 2026 data: July 2026 was only the eleventh warmest July on record for Europe as a whole, at 20.49°C, because while France, Spain, England and Ireland baked, eastern Europe and Scandinavia ran cooler than average. Europe’s summers are increasingly a west-east story, not a north-south one.

The natural calendar: blossom, lavender, foliage, snow

These are the dates people plan whole trips around, and they are the ones worth pinning down before you book flights.

What	When	Notes
Mallorca almond blossom	Late January to February	Mid-February is usually the single best week
Keukenhof tulip gardens, Netherlands	18 March to 9 May 2027	Peak bloom roughly 10 to 30 April, absolute peak 13 to 25 April
Bonn cherry blossom, Germany	Late March to late April	Peaked around 1 to 12 April in 2026; peak lasts 10 to 14 days
Copenhagen cherry blossom	Mid-March to late April	The Sakura Festival at Langelinie ran 18 to 19 April 2026
Valensole lavender, Provence	Mid-June, for about a month	Strongest colour late June into the first fortnight of July
Sault lavender, Provence	July into August	Higher altitude, so it runs later than Valensole
Valensole lavender harvest	From around 15 July	In a hot dry year some fields are cut by about 25 July
Ruska, northern Finland	Second week of September, for about ten days	Moves south at roughly 500 km in a couple of weeks
Ruska, central and southern Finland	Late September into early October	The tail end of the same wave
Midnight sun, Tromso	19 May to 26 July	White nights, never fully dark, run 12 April to 1 September
Polar night, Tromso	28 November to 14 January	The sun does not clear the horizon at all
White nights, Reykjavik	27 April to 15 August	Longest day averages 20 hours 55 minutes of daylight
Val Thorens ski season	21 November 2026 to 2 May 2027	Season opens with La Grande Premiere on 21 and 22 November
Matterhorn Glacier Paradise, Zermatt	Open 365 days a year	At 3,883 m, one of only a handful of places in the Alps with year-round skiing
Hintertux glacier, Austria	Year-round	Austria’s only 365-day ski area

The general rule for blooms is that they move earlier in a hot year. Provence’s 2026 harvest was pulled forward by extreme heat, which caught out people who had booked for the third week of July on the strength of an old blog post. Build a week of slack into any trip whose whole point is a flowering plant.

Where to go in each month instead

The most useful thing a weather table can do is hand you a swap. Same trip, better month, or same month, better place.

If you were planning	In this month	Do this instead	Why
A Riviera beach week	October	Sicily or the Aegean	Nice gets 133 mm of October rain; Athens gets 48 mm and a 22°C sea
Greek islands	August	Late September	Sea still 24°C, air down to 28.9°C, and the July-August crowd surge is over
Anywhere Mediterranean	June, for swimming	Early September	June water is 21 to 22°C; September water is 22 to 24°C
Alpine hiking	July	Early September	Munich’s 132 mm of July rain is afternoon thunderstorms; September is drier and clearer
A Scandinavian city break	December	August	Stockholm’s December afternoon is over by mid-afternoon; its July high is 22°C
Tulips at Keukenhof	Early May	13 to 25 April	That is the absolute peak window; the garden runs to 9 May but late blooms thin out
Provence lavender	Late July	Last week of June	Valensole harvest starts around 15 July and can finish by 25 July in a hot year
Skiing on a budget	February half-term	Third week of January	Same snow, between the Christmas and half-term price peaks
Northern lights	December	February	Same aurora odds, but the light is back for daytime landscape and the cold is manageable
Southern Spain or Portugal	August	March or April	Madrid’s July high is 31°C; April is 18°C and far quieter

Picking a month by what kind of traveller you are

• First trip to Europe. May or September. Long days, moderate temperatures, everything open, prices below peak. Start with how to plan a trip to Europe and a Europe itinerary that does not try to do six countries.
• On a tight budget. Late January to early March, or November. The EU’s August-to-January overnight-stay ratio of 3.6 to one is a price signal as much as a crowd one. See Europe on a budget and the cheapest places to travel in Europe.
• With kids. Late June or early September if you are tied to school terms, and northern Europe rather than southern in August. Europe with kids has the age-by-age version.
• Beach and swimming. Late July to early October, with September the sweet spot on every measure except air temperature.
• Cities and museums. October to March. Shorter days, but no queues, and rain matters less when the plan is indoors. European city breaks covers the weekend versions.
• Hiking and the outdoors. June for wildflowers and long days, September for stable weather and clear air. Avoid July in the Alps unless you like afternoon thunder. See hiking in Europe.
• Skiing. January for value, February and March for reliable snow, late April for spring conditions at altitude.
• Solo. May, June and September, when hostels and group tours are running but not yet full.
• Road trips. May, June and September, with the caveat that high Alpine passes are often shut until late May or June. Europe road trips has the routes.

The warmest place in Europe in winter is not in Europe

Ask which European destination is warmest in January and the honest answer is the Atlantic islands: the Canaries and Madeira, both politically European, both geographically off the coast of Africa, and both roughly six degrees warmer in winter than anywhere on the Mediterranean.

Lanzarote and Tenerife South run a 21 to 22°C daytime high in January against Athens’s 14°C and Lisbon’s 15°C. Rain in the southern Canaries is close to nothing: Fuerteventura averages 85 mm a year, and May through September are effectively dry. Tenerife South and Fuerteventura each get around 2,870 to 2,920 hours of sunshine a year, which is more than Athens.

The trade-offs are real and worth stating. The sea is cooler than the Mediterranean in summer, around 22 to 24°C at its best, because a cool current runs past the islands. The north-facing slopes are cloudier and wetter than the south: Funchal in Madeira gets 105 mm of rain in January and 645 mm a year, which is more than Athens gets. And in July and August the eastern Canaries can get a calima, a Saharan dust episode that pushes temperatures past 40°C and fills the air with sand. Madeira has its own version, the Leste, from June to October.

Madeira is the mild one rather than the hot one: Funchal’s daytime highs sit at 20°C from December through March and only reach 27°C in August. Its sea peaks at 24°C in September and is properly swimmable from August to October. If you want winter walking rather than winter sunbathing, that is the profile you want.

The named winds, and the months they show up in

Southern Europe’s weather is often not about the season but about which wind is blowing. These are seasonal enough to plan around:

• The mistral, in Provence and the Rhone valley. A cold, dry northerly that can blow for days, most often in winter and spring. It brings brilliant clear skies and makes a 15°C day feel like 8°C. It is why Provence is so bright in March and why the Rhone valley is a wind-farm corridor.
• The bora, on the Croatian and Slovenian Adriatic. A cold gusty north-easterly, strongest from autumn through early spring, capable of closing coastal roads and cancelling island ferries. If you are island-hopping in Croatia in November or March, build a spare day into the plan.
• The sirocco, from North Africa across Malta, Sicily and southern Italy. A hot, humid, dust-laden southerly, most common in spring and autumn, which can add ten degrees and leave a film of red dust on everything.
• The meltemi, in the Aegean. A strong dry northerly that blows through July and August, at its most persistent in the central Cyclades. It is the reason August in Greece is often more bearable than August in Rome, and also the reason your Mykonos to Naxos ferry gets cancelled.
• The calima, in the Canaries. Saharan dust and heat, most frequent in July and August, and the one weather event that genuinely spoils a Canaries week.

These are qualitative descriptions rather than measured figures. I have not put frequency numbers on them because I could not find a source I trusted for the whole set, and a made-up number is worse than none.

Six mistakes people make reading Europe weather by month

1. Treating an average as a forecast. Every number in this article is a long-term normal, usually a thirty-year one. Rome’s July average high is 32°C; Rome has been 40°C in July. Averages tell you what to pack, not what will happen.
2. Booking a beach trip on air temperature. Air and sea are two months out of phase. May air can be 24°C with 18°C water; October air can be 22°C with 21°C water. Check the sea table.
3. Assuming Mediterranean winter is warm. Athens in January averages 14°C by day and 7°C at night, and many buildings in southern Europe are built to shed heat rather than hold it. Indoors can be colder than you expect.
4. Ignoring daylight. A November trip to Edinburgh and a November trip to Seville are not the same trip, even at similar temperatures, because one of them is dark from mid-afternoon.
5. Thinking the Alps are dry in summer. Zurich gets 115 mm in July and Munich 132 mm, both wetter than either city’s January. Alpine summer is thunderstorm country.
6. Using pre-2020 heat expectations. Four of Europe’s warmest Junes on record have happened in the last handful of years, and 2026 broke the record set in 2025. Plan southern European summers around the heat, not in spite of it.

Final thoughts

The single most useful shift you can make is to stop asking when to visit Europe and start asking when to visit a specific climate zone. There is no month that is good for the whole continent and no month that is bad for all of it. December is dreadful in Stockholm and lovely in Vienna. August is unbearable in Seville and superb in Tromso. October is glorious in Athens and a washout in Nice.

If you want one rule: for a general trip, book May or September. For beaches, book late September. For cities and museums, book November to March and go somewhere that is good in the dark. For snow, book January or March rather than February. And whatever month you choose, check the sea table before you pack a swimsuit and the daylight numbers before you pack an itinerary.

Two gaps I should name rather than paper over. I could not source month-by-month normals for a high Alpine resort such as Zermatt or Interlaken, so the Alpine rows here are valley cities (Zurich, Munich, Vaduz) rather than altitude; add roughly 0.6°C of cooling per 100 m of ascent if you need a rough figure. And several cities in the temperature table are missing from the sunshine or rainfall tables because the underlying datasets do not carry them. I have left those cells out rather than filled them with estimates.

For the strategic version of all of this, read my pillar guide on the best time to visit Europe, then pick your season: spring, summer, autumn or winter. If crowds are your main concern rather than weather, the least crowded time to visit Europe is the companion piece to this one.

Country guides, by climate zone

Weather is only half the decision. These are the country guides that go with each of the five zones above:

• Northern and Nordic: Iceland and Scandinavia and the Nordics.
• Western and Atlantic: France, the United Kingdom, Ireland and the Netherlands.
• Central and Alpine: Germany, Austria and Switzerland.
• Southern and Mediterranean: Italy, Spain, Portugal, Greece and Croatia and the Adriatic.
• Eastern: Central and Eastern Europe and Turkey and Istanbul.

And for the mechanics of the trip itself: train travel in Europe, getting around Europe, where to stay in Europe, what to pack for Europe, Schengen visa and ETIAS rules and general Europe travel tips. And if you plan trips around what is in season on the plate, what to eat where in Europe tracks which regions peak in which months.
