After a more comfortable weekend, the weather in Paris and Île-de-France is once again forecast to be very summery for the week of July 27 to August 2, 2026. The sun is expected to dominate, before a noticeable rise in temperatures in the second half of the week and a risk of another heatwave.
The cooler spell seen this weekend is not expected to last. According to forecasts from Météo-France, high-pressure conditions will gradually reassert themselves over the Paris region, bringing dry weather and increasingly hot.
If the week starts off pleasant, temperatures could quickly rise from Wednesday, in a context of strong heat affecting a large part of France.
Monday 27 et Tuesday 28 July 2026, the sky is expected to be largely sunny despite a few harmless clouds. Temperatures will stay near the seasonal norms on Monday, with highs around 27°C, before a first rise on Tuesday when the mercury could reach 31°C. Nights will remain fairly cool, between 16 and 18°C, offering a bit of relief.
Ideal conditions to enjoy the swimming spots along the Seine and Marne or head to the Joinville-le-Pont beach in Val-de-Marne.
The most noticeable change is expected to begin on Wednesday, July 29. Forecasts point to a fresh surge of heat, with temperatures rising to around 35 to 36 C in Paris and the Île-de-France region. Thursday and Friday are expected to bring very high values, under largely sunny skies. An unsettled, thunderstorm-prone trend remains possible later in the week if the air becomes more unstable.
Two perfect sunny days to enjoy refreshing outings in Paris and Île-de-France, or to take in the Olympic basin at the Jardin des Tuileries, open all summer until September 14, 2026.
At this stage, forecasts are still being refined, but the weekend could extend this episode of heat waves. Models still anticipate temperatures well above seasonal norms, even though a cooldown accompanied by storms isn’t entirely ruled out depending on how the air masses evolve. As is customary at this juncture, these trends will need to be confirmed in the upcoming bulletins from Météo-France.
So, before you head out, check the Paris metro and RER travel updates here: Paris metro and RER transport news and then consult the day’s headlines for Paris and Île-de-France: news and updates for Paris and Île-de-France. Also keep an eye on air quality in Île-de-France with Airparif, which can be affected by heat waves. Ozone pollution in Île-de-France remains a key indicator to monitor on sunny, hot summer days.
This week, from July 27 to August 2, 2026, looks ideal for outdoor activities at the start, but we should stay alert to the probable return of significant heat by midweek. We’ll continue to consult the Météo-France weather vigilance map and the practical guidance from Santé Publique France for hot days. To keep up with daily forecasts, Météo-France remains the reference.
