Paris, July 15, 2026 – The heatwave gripping Paris and the Île-de-France region has seen a slight reduction in intensity, with Météo-France lowering the vigilance level from red to orange. This change took effect at 6:00 AM on Wednesday, July 15, 2026, across all eight 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 Relative Reprieve Amidst Persistent Heat
Despite the downgrade, the heatwave episode is not over. Météo-France, in its bulletins issued late Tuesday, July 14, 2026, described the event as severe and prolonged, with an air mass that remains hot. The reported temperature drop is considered “very relative” until Thursday, with a more significant respite expected thereafter.
Temperatures Still High Across the Region
As of Tuesday at 3:30 PM, Météo-France recorded temperatures of 33.3°C in Paris-Montsouris, 36.6°C in Saint-Maur (94), 35.5°C in Neuilly-sur-Marne (93), and 33.2°C in Suresnes (92). In the outer suburbs, temperatures were even higher, reaching 36.4°C in Nemours, 35°C in Fontainebleau (77), and 35.8°C in Milly-la-Forêt (91).
For Wednesday, anticipated maximum temperatures range between 32 and 34°C in Paris and the inner suburbs, between 32 and 35°C in Seine-et-Marne, between 32 and 33°C in Yvelines, and between 31 and 33°C in Val-d’Oise. The preceding night remained oppressive, with minimums between 19 and 24°C, indicating another tropical night for much of the region, lacking the necessary coolness for recovery.
Recommendations Remain Crucial Under Orange Alert
The transition from red to orange vigilance does not signify the end of the alert. The orange level still indicates a real risk for vulnerable individuals, including the elderly, infants, pregnant women, and workers exposed to heat. Health authorities reiterate essential precautions:
- Drink regularly without waiting for thirst.
- Keep homes closed and shutters drawn during the day, ventilating at night.
- Avoid physical exertion during the hottest hours.
- Check on isolated family and friends.

The Canicule info service platform remains reachable at 0 800 06 66 66 (free call), and the ARS Île-de-France and Santé publique France continue to relay official recommendations. In Paris, cool havens such as parks, churches, swimming pools, and air-conditioned museums remain the best allies for the coming days.
Impact on Public Spaces and Services
The region has endured a particularly challenging period, marked by water restrictions, forest fires, and strained public transport. This Wednesday offers a temporary reprieve, but not yet a return to normalcy. Caution is still advised until Thursday, when a more noticeable drop in temperatures is expected.
Several cultural institutions have adjusted their operations due to the heatwave:
- Grandes Serres and Ménagerie of the Jardin des Plantes: Closed to the public from July 11, 2026, until the end of the red heatwave alert.
- Musée Gustave Moreau: Closed until Monday, July 13, 2026, inclusive.
- Musée Jean-Jacques Henner: Temporarily closed until Monday, July 13, 2026, inclusive.
- Louvre Museum: Anticipated early closure from July 10 to July 13, 2026, closing at 4:00 PM instead of 6:00 PM to ensure the comfort of visitors and staff.
These measures reflect the ongoing efforts to mitigate the effects of the prolonged heatwave on both public health and daily life in the French capital and its surrounding region.
