The weather in Paris and Île-de-France is zigzagging like a roller coaster this week, October 5–11, 2026. On Monday and Tuesday, sunshine and highs around 25°C give the capital a late-summer feel. From Wednesday, rain returns and thermometers drop by about ten degrees. Paris (75), Hauts-de-Seine (92), Seine-Saint-Denis (93), Val-de-Marne (94) and the entire Île-de-France region are living through this change of scenery.
We map it day by day, drawing on forecasts from Météo-France and the expert outlooks from Météo Paris, updated this Sunday, October 4.
The week starts off under a clear sky. Météo-France is forecasting dry, largely sunny conditions for the capital, with morning temperatures around 14°C and an afternoon rise to the mid-20s, about 24–25°C. Winds will be light, making it perfect for a terrace lunch without needing a jacket.
This spell of mild weather is explained by a southwest flow that is ushering in warmer air across a wide swath of the country, as weather service Météo Paris explains. The trend is more pronounced in the Southwest, where readings are locally close to 30°C.
Yes, Tuesday, October 6, 2026 bears a strong resemblance to the day before. Forecasts put the temperature at 13°C at dawn and 25°C in the afternoon, with no rain expected. It’s the last truly mild day of the week, and it sits well above the typical early-October norms.
A storm system is being watched for Tuesday and Wednesday, with the focus shifting first to the southwest quadrant of the country, then to the south and east, according to the Météo Paris analysis. Île-de-France is not on the front line, but the track of this cold drop remains uncertain. A quick look at the Météo-France vigilance map before setting out is a good habit.
Wednesday, October 7, is the day the weather shifts. Météo Paris forecasts 10 to 15 millimeters of rain for the capital, making it the wettest day of the week. Highs will dip to 17°C, a real change in atmosphere after 25°C the day before.
These showers arrive on soil that has been extremely dry. Météo-France has just released its climate assessment for September 2026, highlighting exceptional heat and a historic drought. A few millimeters won’t make up for the deficit, but gardens and parks in the Île-de-France region will welcome the relief.
Today it’s wiser to postpone outdoor excursions and keep an umbrella handy on public transport. To plan your trips in advance, the weekly briefing on disruptions to the metro, RERs and Transilien remains useful.
Not cold yet, but a true freshness is settling in. Thursday, October 8, should be dry with highs around 15°C. Friday, October 9, will bring the coolest start of the week, with about 7°C in Paris and likely a degree or two lower in the outer suburbs—Yvelines, Essonne, or Seine-et-Marne.
The temperature dropping from 25 to 15 degrees in 48 hours is like autumn arriving in one sudden rush, waiting behind the door to step in. The light coat and scarf are back by the entryway.
The weekend is sticking with an autumnal feel. On Saturday, October 10, Météo Paris forecasts temperatures ranging from 12°C to 17°C, with 2 to 4 mm of rain possible. On Sunday, October 11, conditions look similar, with 10°C in the morning, 17°C in the afternoon, and only a few showers expected.
At this point, forecasts remain tentative. Models are still weighing between a prolonged cool spell in the north of the country and a new rise in temperatures before mid-October.
Monday and Tuesday, the terraces and the banks of the Seine invite a sunny break. As early as Wednesday, we’ll lean toward indoor venues: the museums and exhibitions in Paris have enough to fill a rainy day, just like this week’s cinema outings.
For a cool, sometimes damp weekend, we’ve gathered all our ideas in the guide what to do this weekend in Paris and Île-de-France, updated each week.
Forecasts can change from day to day. The Île-de-France page on Météo-France and the weather vigilance service are updated several times a day to monitor developments as closely as possible.
