After a week of high tension, the Île-de-France region returns to yellow heatwave vigilance this Monday, June 29, 2026. Since 6am, Météo-France has downgraded 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), which are leaving orange. It’s a sign that the heatwave episode is coming to an end for the region.
The switch is due to a shift in air masses. The warmest air is now moving eastward across the country, while cooler air advances from the west and northwest. As a result, temperatures fall and the region's pressure eases.
The orange heat alert now affects only a handful of southern departments (Alpes-de-Haute-Provence, Alpes-Maritimes, Var and Corsica), where the heat remains intense. In Île-de-France, the switch to yellow simply calls for vigilance, with no special restrictions.
After the weekend's violent storms, which at times put the region on alert and prompted the closure of several parks and green spaces, the risk is easing. On Monday, the remaining storm activity is mostly confined to the northeast of the country late at night.
These rains, the first since the start of the episode, were a relief for a parched, heat-stricken region. They also swept away the hot air that had built up, speeding the return to more breathable conditions.
This Monday, June 29, 2026, clearly signals the end of the first heatwave. Daytime highs are gradually easing back to more bearable levels, far from the national records set on June 24 and 25, among the hottest days ever recorded in France.
A word of caution still applies: homes that have baked under the heat for more than a week will take a few days to cool down. And the real question for what lies ahead remains: la canicule va-t-elle revenir en juillet en Île-de-France ? To follow the evolution hour by hour, we’re keeping an eye on the carte de vigilance Météo-France.
That's the other piece of good news. The heatwave–driven ozone pollution episode that accompanied the heat is over: according to Airparif, concentrations have fallen back below the information threshold. The police prefect has therefore lifted, by decree, all emergency measures, including the differentiated traffic, since 6 a.m. on Sunday, June 28, 2026.
In practical terms, all vehicles can resume normal operation in the region, with no Crit'Air vignette restrictions or reduced speed limits. Real-time air quality can be checked on Airparif's website, and updates can be followed on the Police Prefecture site.
Even at yellow alert, we don’t let our guard down right away, especially for the elderly, children, and people living alone. The recommended precautions remain the same until the heat has fully subsided:
