Paris Weather: How to Survive Every Season

In short. Paris has a temperate oceanic climate with four distinct but unpredictable seasons. Summer (June-August): 22-30°C (72-86°F), heatwaves up to 40°C (104°F), possible afternoon thunderstorms. Autumn (September-November): mild and rainy, 10-18°C (50-64°F), beautiful foliage. Winter (December-February): 3-8°C (37-46°F), rare snow but damp cold that gets into your bones, rarely below -5°C (23°F). Spring (March-May): 10-20°C (50-68°F), alternating sun and rain. Paris has 160 rainy days a year on average, spread across every season: a compact umbrella is essential year-round. The "felt" temperature is usually lower than the actual one due to wind and humidity: dress in layers. In August many shops and restaurants close for annual holidays ("fermeture annuelle").

One of the things tourists often discover too late is that Paris weather is mischievous. You leave in the morning with sunshine, by 2 PM there's a downpour, by 5 PM the sun is back, by 7 PM it's cold. All in one day. If you go to Paris expecting the postcard climate of August in any month, you'll be disappointed. If instead you prepare with a bit of logic, you discover that every season has its charm — and Parisian autumn, in particular, is one of the most beautiful things in Europe.

What's the climate like in Paris?

Paris has a temperate oceanic climate (Köppen classification: Cfb), influenced by the Atlantic which brings humidity year-round. The main characteristics are mild summers, cool but rarely freezing winters, rainfall distributed across the year, and frequent wind. There are never extremes (like Berlin's icy winters or Madrid's scorching summers) but the daily variability is high: three-day forecasts are reliable, weekly ones often aren't.

Annual averages from Meteo France: average annual temperature 12.3°C (54°F), 160 rainy days on average per year (but rarely intense: brief frequent rains), 1,660 hours of sunshine per year, relative humidity around 75%.

The urban heat island effect makes Paris on average 1-3°C warmer than the surrounding countryside, especially summer evenings. Wind is frequent, especially in autumn and winter: wide streets (Champs-Élysées, Concorde) amplify it like a wind tunnel.

What's the weather like in Paris in spring?

Spring in Paris (March-May) is the most unpredictable season. March can swing from 5°C rainy to 18°C sunny in two days. April is usually mild but with frequent surprise rain. May is the perfect season: 14-22°C, blooms everywhere, long days, full parks.

What to pack: layered clothing. Sweater or cardigan, light waterproof jacket (a trench or a windbreaker), one pair of light pants and one medium, comfortable waterproof shoes. Compact umbrella always in your bag. Evenings can still feel cool: a light scarf makes the difference.

What to enjoy: the parks reflower (Luxembourg, Tuileries, Buttes-Chaumont, Bois de Vincennes), the cherry blossoms in April are spectacular, the café terrasses reopen. Spring is also exhibition season at museums and outdoor concerts.

What's the weather like in Paris in summer?

Summer in Paris (June-August) has average temperatures of 22-26°C (72-79°F) during the day, 15-18°C (59-64°F) at night, and very long days (in June the sun sets after 9:30 PM and light lasts until 10:30 PM). Generally pleasant, with the occasional summer afternoon thunderstorm.

The most significant weather event is the canicule (heatwave). August can hit peaks of 35-40°C (95-104°F), and these periods have become more frequent in recent years due to climate change. When the canicule arrives, many Paris buildings have no air conditioning — especially old apartments, the metro (except lines 1, 4, and 14), many small restaurants. Surviving requires strategies: drink constantly, avoid the metro in the hottest hours (tunnels can exceed 40°C), seek out parks and the Seine banks, frequent air-conditioned museums in the worst hours.

What to pack: light clothing, but also a light sweater for evenings (the day-night difference is significant), comfortable breathable shoes, a pair of longer pants for cool evenings or restaurants where shorts aren't appreciated, sunglasses, sunscreen, water bottle for tap water.

Plus: in August in Paris many shops, restaurants, and hair salons close for annual holidays (fermeture annuelle). It's the great Parisian migration toward the sea and the mountains. Streets empty out, neighborhood boulangeries close for two-three weeks, bistro restaurants put up the sign. In less touristy zones, August can feel like a ghost town. Central tourist areas stay open.

What's the weather like in Paris in autumn?

Autumn in Paris (September-November) is probably the favorite season of Parisians themselves and of many experienced travelers. September is warm and sweet (18-25°C), October is the queen of autumn: 12-18°C, leaves changing color in every park, warm afternoon light, romantic atmosphere. November starts to cool down (8-14°C) and gets rainier.

Paris parks are spectacular in autumn: the Jardin du Luxembourg, the Tuileries, the Bois de Vincennes, Père-Lachaise (the monumental cemetery is beautiful in autumn) fill with red, orange, yellow. A walk along the Seine in late October at sunset, with fallen leaves, is one of those things that stays in your memory forever.

What to pack: sweater, medium jacket, rain jacket or waterproof always, jeans or medium pants, scarf, closed waterproof shoes. Compact umbrella permanently in your bag (in Paris October rains more than March). Evenings get cool: light cap or beanie.

Autumn in Paris is also the season of cultural events: Nuit Blanche (museums' white night) at the start of October, Paris Photo in November, opera premieres, concerts at the Théâtre des Champs-Élysées. The city is alive culturally like no other time.

What's the weather like in Paris in winter?

Winter in Paris (December-February) is cold but not freezing. Average temperatures are 3-8°C (37-46°F) during the day, 0-3°C (32-37°F) at night. Below -5°C happens only a few days a year, and snow is rare: it really snows maybe 2-3 times all winter, and usually melts within 24 hours.

The problem with Parisian winter isn't the thermometer, it's the humidity and wind. The damp cold gets into your bones, and 5°C in Paris can feel like -2°C in a drier city. Add the short days (sun setting at 5:00 PM in December, around 5:30 PM in January) and you understand why many tourists find it tough. But there's another side: Paris under the Christmas lights, the department store windows (Galeries Lafayette and Printemps put up wonderful installations), the Christmas markets on the Champs-Élysées and at Notre-Dame, the atmosphere of cafés inside with the fireplace lit — these are things worth the trip.

What to pack: heavy coat or medium puffer, wool sweater, scarf, gloves, beanie, waterproof warm shoes (never canvas sneakers), heavy fabric pants, wool socks. Sturdy umbrella (Paris rains in winter too, sometimes mixed with snow). Thermal undershirt if it's very cold.

The first two weeks of January are often the toughest: holidays over, damp cold at its peak, very short days. From mid-February you start seeing slightly longer sunny days.

How much does it rain in Paris during the year?

Paris has 160 rainy days on average per year (Meteo France), but they're usually not intense rains: Parisian rain is more a prolonged drizzle than a violent downpour. The rainiest months are May, October, and December, but the difference between the rainiest (May, 65 mm) and the driest (February, 41 mm) is smaller than you'd think.

In practice: in every season there's a non-negligible chance of rain during the day. That's why a compact umbrella is considered mandatory year-round by Parisians, and they're sold in metro convenience stores for €5-10.

Local trick: if you see a dark grey sky approaching, step into a café. Parisian rain usually lasts 30-60 minutes. You sit down, get an espresso, wait it out, and when you come out the sun is back.

How do I plan a Paris day around the weather?

The trick is low-tech: check a reliable hourly forecast the night before (Météo-France or your phone's weather app), then front-load the outdoor stuff into the dry hours and save the indoor stops for when rain is likely. If the forecast says clear morning and showers from 3 PM, do the gardens, the riverside, and Montmartre's streets early, and line up a museum, a covered passage, or a long brasserie lunch for the wet part of the afternoon. Paris rewards this kind of planning because so many of its best experiences — the Louvre, Orsay, the covered passages, the department stores, a two-hour bistro lunch — are indoors anyway.

A planning app helps you lay the day out in advance rather than improvising stop by stop. Zeppelin Map (the iOS transit navigation app for Paris, developed by Anaximae SASU) lets you set all your stops ahead of time and even lock one to a fixed hour — a dinner reservation at 8 PM, say — and then it works out the order and the transit between them so the day flows and ends where you want it to. You still decide the weather strategy, but having the whole route mapped before you head out means a sudden downpour just sends you to the next indoor stop instead of leaving you stranded.

Best seasons to visit Paris

If you have to pick one, here's my practical-guide opinion:

May is probably the optimal month: beautiful weather, parks in bloom, still few tourists compared to July-August, long days. Warm but not scorching.

September is the second best: temperature similar to May, traces of summer, leaves starting to change, sweet atmosphere.

October is perfect for those who love autumn colors: spectacular foliage, golden light, romantic atmosphere. Rainier than September but magical.

April is similar to May but with more rain.

July-August is the most touristy and hot season: very high prices, queues everywhere, fermeture annuelle of neighborhood venues, possible heatwaves. But very long days and vibrant atmosphere.

December is magical for Christmas and lights lovers, but cold, damp, short on daylight.

January-February are the quietest and cheapest months: hotels at half price, empty museums, intimate city. But the weather is the worst.

Micro-rules for not getting caught off-guard by Paris weather

• Keep a compact umbrella always in your bag or backpack, in any season. It costs nothing to carry, it's worth a lot when it rains suddenly. Dress in layers: in Paris temperatures vary a lot between day and evening, between inside and outside (where they usually crank heating or air conditioning beyond what's needed). Three thin layers are better than one thick one.

• Good waterproof shoes, always. Canvas shoes or cheap sneakers turn into sponges after five minutes of rain. Ankle boots in winter-autumn-spring, sturdy sneakers in summer.

• Check the weather the night before, not in the morning. The difference between 8°C and 18°C is big, and packing an extra jacket costs nothing. The Meteo France or Météo Paris apps are the most reliable.

• Hat, gloves, scarf in winter: no heroics, it really is damp cold. Sunscreen even in spring-summer, even when it's cloudy (UV rays pass through).

• Water bottle for tap water (it's excellent and free in Paris), very useful in summer. Cap or beanie in winter, sunglasses in summer.

The real question: when to go to Paris?

The honest answer: there's no bad time to go to Paris. Every season has its charm. May and October are the closest to "perfect," but even a dark December with Christmas markets or a scorching August with a half-empty city has something special. The secret is to prepare for the weather you'll find, not complain about the weather you didn't.

And remember: most of the monuments, museums, and most beautiful restaurants in Paris are indoors or covered. Even with rain, a Paris week can be splendid. Even with snow. Even with a heatwave, as long as you know how to move in the right hours and have strategies to survive the heat.
