The weather in Paris and Île-de-France cette semaine du 24 au 30 août 2026 is set to swing between heat, humidity, storms and a cooling trend. After a relatively milder end to the previous weekend, temperatures will rise again briefly, peaking at 28°C in Paris on Monday and Tuesday, before a pronounced drop in the mercury from Thursday, and especially on Friday.
This development sits within a broader weather picture. Météo-France had already warned on August 21 of a new rain-and-thunderstorm outbreak from the west at the start of the week. On the Île-de-France level, the latest Météo-Paris forecasts point to a remarkably unsettled week, with several thunderstorm risks before a cooler Atlantic air mass takes over.
Across the eight Île-de-France departments (75, 77, 78, 91, 92, 93, 94 and 95), the contrast will be pronounced. In Paris, temperatures would swing from 28°C on Monday to just 20°C on Friday, before a mild rebound over the weekend.
This Monday, August 24 ushers in a return of summer weather. In Paris, temperatures are expected to hover between 16°C in the morning and 28°C in the afternoon.
But the sun won't be the only feature in the forecast. Clouds rolling in from the south will gradually fill the sky, and a first shower remains possible in the morning. A new disturbance could then affect the region in the evening and overnight, with a risk of thunderstorms.
Based on the detailed forecast for Paris and the Île-de-France region, the chance of precipitation is pegged at 30%, with possible rainfall totals of 2 to 4 mm.
More ways to enjoy the Parisian parks and gardens by day, while keeping an eye on the sky as evening approaches.
On Tuesday, August 25, the heat remains well in place with around 17°C in the morning and 28°C in the afternoon. After a few final showers possible at dawn, a lull should prevail for much of the day.
But unsettled conditions could resume late in the afternoon, in the evening and overnight, with a risk of isolated storms moving up from the south.
Wednesday, August 26, the atmosphere will stay heavy and frequently overcast. In Paris, temperatures will range from 18°C to 27°C. Rain should be limited during the day, but another storm system could develop overnight.
If the weather turns for the worse, it could be an opportunity to opt for Parisian museums instead of an extended outdoor outing.
Thursday, August 27 is currently one of the days to watch most closely.
A more organized thunderstorm complex could sweep across Paris and the Île-de-France region by the end of the day. Temperatures would likewise start to fall, with around 18°C in the morning and 24°C in the afternoon.
The latest forecasts from Météo-Paris put the rain risk at 70 %, with rainfall totals of 6 to 10 mm possible.
Even several days out, predicting the intensity and, above all, the exact location of the storms remains tricky. So you’ll need to regularly check the Météo-France vigilance map in case of potentially dangerous weather.
Yes, and the shift should be fairly noticeable. By Friday, August 28, temperatures in Paris could stay below 20°C, with dawn readings around 15°C. That marks roughly an 8-degree drop from the start of the week.

Sunday, August 30, little change. The disturbed ocean current is expected to persist with rainy spells, for about 15°C in the morning and 23°C in the afternoon. Here too, the risk of rain is estimated at 70%.
A stroll along the Seine or a trip to the weekend markets remains possible, provided you keep an umbrella within reach.
Several timeframes remain to be watched, notably Monday evening, Tuesday evening and especially Thursday, August 27.
This instability is largely the result of a clash between warm air surging up from the south and cooler air masses advancing in from the west. Météo-France says the rain and thunderstorm outbreak is set to push in from the west as the week gets underway.
That doesn’t mean Paris will inevitably be hit by violent storms. These events remain highly localized, and their paths can still shift quickly.
The prudent move is to regularly consult the carte de vigilance de Météo-France, especially before an outing or an outdoor event.
To monitor how the situation unfolds over the week, you can check the Météo-France bulletin as well as its official vigilance map.
Analysis from Météo-Paris.com, led by meteorologist Guillaume Séchet, also provides an in-depth look at forecasts for Paris and the entire Île-de-France region. The site notes that its multi-day outlooks are regularly refreshed and vetted against the latest model scenarios.
In short, the week of August 24–30, 2026 looks set to be unusually unsettled in Paris and Île-de-France : heat and humidity through Wednesday, a pronounced risk of storms on Thursday, then a noticeable cool-down Friday. The weekend is expected to remain mixed, with showers and temperatures around 21–23°C. So keep your umbrella handy to enjoy Paris, even as the sky stays a little capricious.
