The red heatwave alert is about to blanket all of the Île-de-France. Météo-France confirmed on this Friday, July 10, 2026 that Paris (75) and the seven other Île-de-France departments (77, 78, 91, 92, 93, 94 and 95) will switch to red starting at noon on Saturday, July 11. The shift also reaches the Centre-Val de Loire region and the Orne department (61), underscoring that the episode is spreading and taking hold.
The mechanism is well known: a very hot air mass has been lingering over the country for several days, in a largely stagnant anticyclone that changes little. As a result, temperatures are rising once again and the heat is set to endure.
Météo-France is warning of a severe and prolonged heatwave, requiring particular vigilance for sensitive or exposed individuals. It is precisely this combination of intensity and duration that justifies the shift to red alert.
This Friday afternoon, thermometers are already reading 34 to 36 degrees across the region, with isolated spots hitting 37 in Paris. Saturday is set to be even hotter, with highs between 35 and 37 degrees in most departments.
The southern part of Seine-et-Marne (77) is among the hottest areas, with temperatures potentially peaking at 38°C. The real test, however, is the night: by Saturday dawn, minimums will stay between 20 and 23°C in Paris and the inner suburbs. This lack of nocturnal relief makes the spell especially hard to bear.
The canicule persists at least into early next week in Île-de-France. Nationwide, Météo-France says it will hold steady until midweek, with a cooling trend possible to begin on the western coast of the country as soon as Tuesday or Wednesday.
For the Île-de-France region, residents will have to wait a few more days before any real relief arrives. We break down the timeline in our article dedicated to the end of the heatwave in Île-de-France.
In the face of these conditions, people should adopt the right habits: stay hydrated, avoid strenuous activity during the hottest hours, close blinds and windows during the day and air the rooms at night, and check in on elderly or isolated relatives. If in doubt, the Météo-France vigilance map and the Canicule Info Service number (0 800 06 66 66), open from 9 a.m. to 7 p.m., remain reliable references.
To take a break, head to the region's pools, leisure centers, shaded parks, and air-conditioned spots, all highlighted in our guide to the best ideas for cooling off in Paris and Île-de-France. Under a red alert, authorities are stepping up patrols at bathing sites and restricting access to cooling islands, while some outdoor events may be postponed or canceled.
