Paris When It’s Hot: 15 Ways to Beat the Heat

Are you in Paris when it’s hot? Like, really hot? Then you are in the right place, because I am sharing my best tips on how to cool down, stay comfortable, and still enjoy the city.

Because Paris is incredible—even in summer. But like any big city, it can feel stifling when the heat kicks in.

I found that out the hard way—moving into my first Paris flat during the July 2006 heatwave. It was 37°C, and I was carrying boxes up three flights. No elevator. No fan. Just sweat and a few regrets.

Since then, I’ve learned how to deal with the canicule. It hits almost every year now, but thankfully, it doesn’t last forever.

And if you plan your days right, the heat won’t ruin your trip.
In this article, I’m sharing my go-to tips for staying cool in Paris—without missing out on what makes the city worth being here for.

How Hot Does It Get in Paris in Summer?

Paris can get seriously hot in summer, but it’s not a tropical climate. You won’t get 30 days straight of blazing sun.

Instead, it’s a mix. Expect mild ups and downs, with temps shifting between hot days, cooler spells, and the occasional storm.

Typical highs in July and August sit around 25–28°C (77–82°F). But during a canicule, it can spike to 35°C (95°F) or even higher.

You’ll also get rain days, which often come with humid air and evening thunderstorms. Some days drop below 20°C (68°F), especially early in the season or after rain.

So yes, Paris gets hot—but not consistently. It’s that unpredictable swing that makes it tricky. One day you’re sweating in the sun, the next you need a light jacket.

What is a Canicule?

If you’re in Paris during summer, you’ll likely hear the word canicule. It’s not just a hot day—it’s a full-blown heatwave.

A canicule means several days of high heat, with little to no cooling at night. That’s when it starts to feel oppressive, especially indoors.

Climate change didn’t invent it, but it made it a regular. Twenty years ago, heatwaves were rare. Now, they show up almost every summer—once in June, again in late July or August, and sometimes a third time just for fun.

The alert kicks in when temps stay above 31°C (88°F) by day and 21°C (70°F) at night, for three days straight. Paris turns into a slow cooker, with heat clinging to every stone wall and street corner.

Uncomfortable? For sure. Dangerous? Sometimes. But there are plenty of ways to keep cool and still enjoy your time out.

Paris When It’s Hot: 15 Smart Ways to Stay Comfortable

When it’s too hot to wander aimlessly or sit on a terrace, you need a plan. Some parts of the city stay surprisingly fresh, others give you proper shelter. From cool museums to shaded parks and late-night breezes by the Seine—here’s how to spend a full day in Paris without melting. Because despite the occasional heat, summer is a great season to visit Paris.

#1 Book a Room with Air Conditioning

Not really an activity—but absolutely essential if you want to stay comfortable.

AC in Paris is not standard. Especially not in private apartments. Hotels are slowly catching up, but you can’t assume it’s included.

If it’s not clearly mentioned, it’s probably not there. I always recommend booking a place with aircon if you’re coming between June and September.

During a canicule, the heat doesn’t ease up at night. You’ll want a cool room to sleep in—not one where you stick to the sheets. I live in a place without AC, and trust me, it’s not my favorite time of the year.

#2 Retreat to the Shade in Parisian Gardens

Parisian gardens are made for summer—especially the really hot days. While wide-open lawns like Champ de Mars near the Eiffel Tower offer little shade, other parks are much more inviting.

Head to Jardin du Luxembourg or Parc Monceau—both have plenty of trees, benches, and quieter corners to cool off.

Parc Georges Brassens in the 15th is less known and perfect for a slow afternoon picnic.

Bring water, fruit, and a book. Find a shady spot and stay still. That’s how locals survive the heat.

#3 Relax at Paris Plages

When the heat makes the city slow down, the riverside becomes the perfect escape. Paris feels different in summer—quieter, more open. Many locals are away, but those who stay gravitate to the water.

Paris Plages sets up each July and August along the Seine and the Canal de l’Ourcq. Think deckchairs, shady spots, beer gardens, and those mist-spray arches that make a real difference.

There’s even a swimming area at the Canal, but it’s limited to Paris residents. Still, the vibe is easygoing, especially in the evening.

I personally like the stretch just below the Musée d’Orsay, where Rosa Bonheur has a riverside spot with chilled rosé wine, Pizza, music, and a relaxed crowd.

It’s not a beach, but on a hot day, it’s the next best thing.

#4 Cool Down with Proper Ice Cream

Ice cream isn’t the first thing people associate with Paris—but it should be. There are plenty of excellent spots if you know where to look.

It’s also one of the simplest ways to cool down during a hot afternoon.

Skip the generic cones from supermarket freezers. Instead, head to one of these:

• Pozzetto – creamy, classic Italian gelato in the Marais
• Moustache – inventive flavors, made with care
• Bachir – Lebanese-style, organic, and served with crushed pistachio on top

These are my go-tos when the city feels like it’s boiling. Grab a cone, find some shade, and slow your pace.

#5 Step Into a Church

Churches aren’t places to spend the whole afternoon—but on a sweltering day, they’re a welcome pause.

Thick stone walls, open doors, and high ceilings mean they stay cool, even when the streets are boiling. You step inside, and the temperature drops instantly.

They’re also beautiful and worth visiting regardless of the weather. But on a hot day, they double as calm, quiet oases.

Try these:

• Saint-Sulpice – elegant and peaceful
• Madeleine – dark, massive, and cool
• Saint-Eustache – grand, but often half-empty
• Saint-Paul-Saint-Louis – baroque, breezy, and right in the Marais
• Sacre Coeur – packed outside, often inside, too.

Even a 10-minute stop can help reset your body temperature—and your mood.

#6 Go Shopping (Somewhere Cool)

During a heatwave, shopping becomes more than retail therapy—it’s a survival tactic.

Most smaller shops don’t have aircon. But the big ones? They’re some of the coolest places in Paris. Literally.

• Galeries Lafayette and Printemps – stylish, massive, and properly air-conditioned.
• Le BHV Marais – quieter, less touristy, and full of odd finds.
• FNAC – ideal for flipping through books, manga, or gadgets in a chilled space.
• Monoprix – not exciting, but when it’s 34°C outside, I’ll happily spend 30 minutes picking out yoghurts.

The heat is honestly the best excuse for a shopping tour. Sometimes you don’t need to buy anything. You just need 20 minutes of refrigerated air.

#7 Indulge in Art (and Air Conditioning)

Museums are cool—literally. And they’re a smart escape when the sun’s too much.

But here’s the trick:
Big museums like the Louvre or Musée d’Orsay can feel as hot as the street, despite running AC. Crowds, body heat, and long waits cancel out every cooling effort. If there is no way around, try visiting in the morning.

Overall, it’s best pick smaller spots:

• Musée Carnavalet – free, quiet, and full of Paris history
• Musée Zadkine – tiny sculpture museum in a garden near Luxembourg
• Musée de Montmartre – off-radar and peaceful, with a beautiful garden
• Musée Jacquemart-André – grand and often overlooked

If you do go to the Louvre, head to the Islamic Art section or the Egyptian wing—both are below ground and cooler.

#8 Cool Off with a Swim

Paris isn’t big on lounging by the pool. It’s just not part of the city’s rhythm. Outdoor pools are rare, and most are built for laps, not sunbathing.

Still, if you’re overheating, they’ll do the job. Here are a few solid picks:

• Piscine Joséphine Baker – a floating pool on the Seine, with nice views. Go on weekdays if you can.
• Molitor – chic and Art Deco. Pricey, but peaceful.
• Piscine Georges Hermant – large, local, and not too busy.
• Piscine Roger Le Gall – basic but reliable, especially if you’re in the east.
• Annette K. – part of a modern gym complex right on the Seine. Quiet in the mornings.

Avoid: Aquaboulevard. It’s packed, hot, and has almost no shade. Looks fun, but not during a heatwave.

You might’ve seen the buzz: starting this summer, the Seine will officially be open for swimming—for the first time in 100 years! Pretty wild, right? It’s not everyone’s idea of a dream dip, but still, a historic moment.

#9 Leave Paris for the Day

It might sound drastic, but sometimes the best way to handle the Paris heat is to get out of it.

In under two hours, you can be at the coast, soaking in a breeze and eating crêpes. There are plenty of lovely spots, but my personal favorites are Étretat and Honfleur—both offer that perfect mix of seaside flair, apple cider, galettes, and cooler air.

Étretat is great for cliff walks and postcard views. Honfleur is more about harbours, terraces, and a slow rhythm.

Also worth a look: Deauville or Dieppe. Trains leave from Saint-Lazare, and it’s honestly a relief to get out for a day.

#10 Seine River Cruise (But Time It Right)

➤ Also Read: 5 Best Seine River Cruise in Paris: Your Ultimate Guide

Seine cruises are a lovely way to see Paris—hot or not. You get a fresh perspective, the pace is slow, and it’s one of the more relaxed ways to take in the city.

But timing matters. Daytime cruises can be a trap. The breeze feels fresh, but sitting in direct sun on the open deck? That’s a quick way to overheat. And if you sit inside to escape it, you’ll miss the best part: the view.

Evening cruises are the way to go.
You get cooler air, golden light, and fewer crowds. It’s a calm, almost cinematic experience.

You can board from:

• Eiffel Tower – Book Bateaux Parisiens
• Pont Neuf – Book Vedettes du Pont Neuf
• Pont d’Alma – Book Bateaux Mouches

#11 Cruise the Canal Saint-Martin

➤ Also Read: Canal Saint-Martin Cruise: Explore Paris Differently!

If you’ve already done the Seine, or just want something quieter, the Canal Saint-Martin cruise is a great alternative.

It’s slower, more local, and winds through shaded tree-lined paths, iron footbridges, and even underground tunnels under Bastille. You certainly get a fresher breeze here.

You see a different side of Paris—less monuments, more hidden corners. And the pace makes it feel like a proper break from the heat.

Boats usually leave near Parc de la Villette or Port de l’Arsenal, and the route is about 2.5 hours.

Less sun, less noise, and a whole lot cooler.

#12 Go to the Cinema

A dark, quiet, air-conditioned room? Yes, please. When the city’s baking, this kind of escape hits differently. The chill, the hush, the screen—it’s the easiest way to forget the heat outside.

Look out for VOST showings (original version with French subtitles) if you want to catch English-language films.

Curious about French cinema but need subtitles? Lost in Frenchlation has you covered. They screen French films with English subtitles in cozy indie theaters.

And even if your French is rusty, you won’t miss out—most cinemas regularly screen VOST versions. Kind of surprising, considering many French don’t speak fluent English—but they love watching films in original versions anyway.

#13 Visit the Catacombs

The Catacombs of Paris aren’t just eerie—they’re a relief when it’s 35°C outside. Underground tunnels, no sunlight, and a steady 14°C year-round. Doesn’t matter if it’s July or January, you might want a jacket.

It’s also one of the most popular sites in Paris, so booking in advance is a must. If it’s already sold out, no worries—just head across the street to the Musée de la Libération. It’s way less crowded and includes actual WWII bunkers used by the Resistance. Also underground. Also cool.

#14 Hydrate, Hydrate, Hydrate

Parisians don’t usually walk around clutching water bottles—but during a canicule, everyone adapts. Luckily, free water’s easy to find. Paris tap water? Cold, clean, and totally drinkable.

You’ll spot Wallace fountains all over—those green, cast-iron beauties from the 1800s. Built to give everyone access to drinking water, and still doing their job today.

Summer upgrade: some fountains now spray cool mist, especially near parks and main squares.

Also good to know: the City of Paris cooling map shows public buildings, shaded zones, and water points across town. Search for “îlots de fraîcheur” online or in the Paris Info app.

#15 Time Your Metro Rides (Or Take the Tram)

➤ Also Read: How to Get Around in Paris: Your Quick Guide

RATP is working on upgrading the metro system, but as of now, not all lines have air conditioning—and when it’s hot outside, the metro can feel like a sauna.

It’s brutal. The air is still, the trains are packed, and everyone’s slowly melting. There’s no breeze, no relief, just heat hanging in the air.

If you can, avoid peak times (8–10 am and 5–7 pm). And stick to these lines where your chances of AC are higher:
Metro 1, 2, 4, 5, 9, 11, 14
They’re either equipped or partially upgraded.

The other lines? Still waiting for that climatisation.

Also: trams are fully air-conditioned. They take longer, but on a hot day, that trade-off is worth it.

Paris in the Heat – Wrap Up

Canicules in Paris are a challenge, no way around that. The heat is dry, the nights are sticky, and the city doesn’t really sleep.

But if you plan smart, you don’t have to suffer through it.

Pick the right accommodation. Schedule wisely. Mix outdoors with cool hideouts. And take breaks—often.

You won’t just survive the Paris heat. You might actually enjoy it.
