Paris, June 29, 2026 – The heatwave’s grip on Île-de-France is finally loosening. Météo-France has reclassified Paris and the entire region to a yellow alert this Monday, June 29, 2026, marking the end of this historic episode with a noticeable drop in temperatures.
Île-de-France Returns to Yellow Heatwave Alert
After a week under high alert, the Île-de-France region has been downgraded to a yellow heatwave alert this Monday, June 29, 2026. Since 6 AM, Météo-France has lowered the alert level for Paris (75), the inner suburbs (Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne), and the outer suburbs (Yvelines, Essonne, Seine-et-Marne, Val-d’Oise), moving them out of the orange alert. This signifies that the heatwave is drawing to a close in the region.
Why the Downgrade to Yellow Alert?
The shift is attributed to a change in air mass. The warmest air is now moving towards the east of the country, while cooler air is advancing from the west and northwest. Consequently, temperatures are falling, and the pressure on the region is easing. The orange alert now only concerns a few southern departments (Alpes-de-Haute-Provence, Alpes-Maritimes, Var, and Corsica), where the heat remains intense. In Île-de-France, the yellow alert simply advises continued vigilance without specific restrictions.
End of Stormy Weather in Île-de-France
Following the severe storms over the weekend, which had temporarily placed the region on alert and led to the closure of several parks and green spaces, the risk has diminished. This Monday, residual stormy activity is mainly confined to the northeast of the country in the late night. These rains, the first since the beginning of the episode, have brought much-needed relief to a parched and overheated region. They also cleared the accumulated hot air, accelerating the return to more breathable conditions.
When Will the Heatwave in Paris and Île-de-France End?
This Monday, June 29, 2026, clearly marks the end of this initial heatwave. Maximum temperatures are gradually returning to more tolerable values, far from the national records of June 24 and 25, which were among the hottest days ever recorded in France. However, a degree of caution remains necessary: overheated homes, after more than a week of high temperatures, will take a few days to cool down. The question of whether the heatwave will return in July in Île-de-France still looms. We will continue to monitor the Météo-France vigilance map for hourly updates.
Pollution and Differentiated Traffic Measures Lifted
Another positive development is that the ozone pollution episode that accompanied the heat has ended. According to Airparif, concentrations have fallen below the information threshold. Consequently, the police prefect has lifted all emergency measures, including differentiated traffic restrictions, since 6 AM on Sunday, June 28, 2026. This means all vehicles can now circulate normally in the region, without Crit’Air vignette restrictions or lowered speed limits. Air quality can be checked in real-time on the Airparif website, and announcements can be followed on the police prefecture’s website.
Heat Safety Tips Remain Relevant
Even under a yellow alert, vigilance should not be immediately relaxed, especially for the elderly, children, and isolated individuals. The same good practices remain essential until the heat has fully subsided:
- Stay hydrated regularly, without waiting for thirst.
- Close shutters and windows during the hottest hours, then ventilate at night when temperatures drop.
- Avoid physical exertion in direct sunlight.
- Cool your body several times a day (mister, wet washcloth, lukewarm shower).
- Remember to check on elderly or isolated neighbors.
