Paris weather: a 5th heatwave with temperatures up to 35°C expected from 10 August
The Paris weather could have another surprise in store for Île-de-France residents as early as the week of 10 August 2026. After a few more bearable days, the intense heat appears ready to make its return. Forecasters are closely monitoring the possible formation of a fifth heatwave of the summer.
A new heat surge expected from 10 August 2026
Forecasts are pointing to temperatures that could reach 34 to 35°C across the region during the week of 10 August 2026. This new heat surge would be driven by the strengthening of a powerful anticyclone over Europe, which would draw very hot air northward from the Iberian Peninsula and North Africa.
The mercury is expected to start climbing over the weekend, before a possible peak between the beginning and middle of the following week. In the south of France, highs could exceed 35 to 38°C. As a result, the Paris Basin would return to levels well above seasonal norms.
The Paris weather and conditions across the greater Île-de-France departments would see maximum temperatures hovering between 33 and 35°C. Nights risk remaining hot if the episode drags on. That said, it is still too early to officially declare a heatwave.
What Météo-France forecasts are saying
Upcoming bulletins from Météo-France will help refine the intensity, duration and extent of this episode. The situation therefore warrants close monitoring in the days ahead. Weather data for Paris will continue to evolve as new analyses come in.
« Les prévisions envisagent une possible cinquième vague de chaleur de l’été, avec des températures susceptibles d’atteindre 34 à 35°C dans la région au cours de la semaine du 10 août 2026. »
For now, no official alert has been issued. That said, vigilance remains essential for the most vulnerable. The coming days will be decisive in confirming whether this episode materialises.
The right steps to take in extreme heat
When temperatures soar, a few simple habits go a long way in protecting your health. You should drink regularly, keep shutters closed during the day and ventilate your home at night. Equally important is avoiding physical exertion during the hottest hours of the day.
- Drink water regularly throughout the day
- Keep shutters closed during the day to limit heat build-up
- Ventilate your home at night to bring down the indoor temperature
- Avoid physical exertion during the hottest hours
- Check in on elderly, isolated or vulnerable people
It is also important to check in on elderly, isolated or vulnerable people. If you feel unwell or experience unusual symptoms, contact emergency services without delay. These reflexes can make all the difference during a severe heat episode.
The Paris weather therefore calls for heightened vigilance from everyone living in the region. Health authorities repeat these guidelines at every heat event. Prevention is always better than dealing with the consequences.
Where to cool down in Paris and Île-de-France
To cope with the Paris weather forecast, several swimming spots and water activity sites are accessible across Île-de-France. In the capital itself, the designated bathing areas along the bras Marie, Grenelle and Bercy stretches of the Seine offer a supervised way to enjoy the river. These spots provide a welcome escape right in the heart of the city.
The leisure islands of Cergy-Pontoise, Vaires-Torcy, Jablines-Annet and Saint-Quentin-en-Yvelines, along with the Créteil leisure base, are among the most popular destinations. Municipal swimming pools, shaded parks, fountains and misting stations also offer further ways to beat the heat. There is an option to suit every situation.
Paris weather: how to stay on top of the situation
With Paris weather this uncertain, it is advisable to check Météo-France’s official bulletins regularly. These updates will progressively sharpen the picture on the intensity, duration and reach of the episode. Each new forecast will bring more precise information on what to expect.
The week of 10 August 2026 is shaping up to be one to watch closely for Île-de-France residents. Temperatures could hit 35°C, which would make this one of the most significant heat episodes of the summer. However, only the next few bulletins will confirm the true scale of this wave.

Keeping a close eye on evolving weather conditions in Paris is the best way to stay prepared.
