After several days of red heat alert, Météo-France announces a shift to orange alert starting at 6 a.m. this Wednesday, July 15, 2026 across all departments of Île-de-France: Paris (75), Hauts-de-Seine (92), Seine-Saint-Denis (93), Val-de-Marne (94), Seine-et-Marne (77), Yvelines (78), Essonne (91) and Val-d'Oise (95). A mixed blessing, because the heatwave itself continues.
In its weather bulletins released on Tuesday, July 14, 2026, in the late afternoon, the institute describes a severe and enduring heatwave within a hot air mass that remains intense. Temperature drops exist, but they are described as “very relative” until Thursday. The real relief, however, is expected to come afterward.
The thermometer still has room to climb. This Tuesday at 3:30 p.m., Météo-France recorded 33.3°C at Paris-Montsouris, 36.6°C at Saint-Maur (94), 35.5°C at Neuilly-sur-Marne (93) and 33.2°C at Suresnes (92). In the greater Paris area, the heat climbed even higher, with 36.4°C in Nemours, 35°C in Fontainebleau (77) and 35.8°C in Milly-la-Forêt (91).
Wednesday's high temperatures are forecast to range from 32 to 34°C across Paris and the inner suburbs, 32 to 35°C across Seine-et-Marne from north to south, 32 to 33°C in the Yvelines, and 31 to 33°C in the Val-d'Oise. The preceding night remains suffocating, with lows of 19 to 24°C depending on the area — in other words, another tropical night for a large part of the region, with no relief to help people recover.
The shift from red to orange does not mark the end of the alert. The orange level still signifies a real risk for vulnerable people: the elderly, infants, pregnant women, and workers exposed to heat. Health authorities urge the public to follow practical precautions: drink regularly without waiting to feel thirsty, keep homes closed and blinds drawn during the day, ventilate at night, avoid any vigorous activity during the hottest hours, and check in on isolated neighbors or relatives.
To monitor the situation in real time, the official map is accessible on the Météo-France Vigilance site, while detailed forecasts are available at meteofrance.com. The Canicule info service platform can be reached at 0 800 06 66 66 (toll-free), and the ARS Île-de-France as well as Santé publique France relay the official recommendations. In Paris, cooling centers, parks, churches, pools and air-conditioned museums remain the best allies for the coming days.
But the region is emerging from a particularly trying spell, marked by water restrictions, forest fires and strained transport networks. This Wednesday signals a lull, not a full return to normal: caution remains warranted until Thursday, when a drop in temperatures is expected to be felt.
The Grandes Serres and the Menagerie at the Jardin des Plantes in Paris have been closed until the end of the alert.
