The red heatwave alert remains in force in Paris (75) and in the seven other departments of Île-de-France: Seine-et-Marne (77), Yvelines (78), Essonne (91), Hauts-de-Seine (92), Seine-Saint-Denis (93), Val-de-Marne (94) and Val-d’Oise (95). In its bulletin released this Sunday, July 12, 2026 at 6 a.m., Météo-France describes a severe and sustained heatwave, driven by a very hot air mass that’s stagnating over the country.
The night has hardly cooled things down. By 5 a.m., temperatures were still around 23°C in Paris-Montsouris, 23.6°C at Orly, 22.7°C at Villacoublay, 21.8°C near Roissy, and 21°C in Melun and Magnanville. In short, the day is already starting hot.
This afternoon, the expected high temperatures vary across the departments, with a clear north-to-south gradient across the region:
For reference, the capital had already reached 37°C on Saturday afternoon. The region remains pegged at the same level, with no let-up in sight.
That's the telltale sign of this spell: the night no longer cools down. In the departments under red alert, the overnight low from Sunday to Monday is projected to stay between 21 and 24°C, with 25°C locally. In Paris and the inner suburbs, dawn temperatures are expected at 23–24°C.
These sleepless nights help explain the move to red status. The body doesn’t recover, and fatigue accumulates day after day, even among people who appear to be in good health.
Monday, July 13, 2026, temperatures edge down slightly but the heat remains intense: 34-36°C in Paris and the inner suburbs, 34-37°C in Seine-et-Marne (with locally up to 38°C), 34-36°C in Essonne, and 33-35°C in Yvelines and Val-d'Oise. The eve of July 14 looks scorching, as several prefectures have already banned fireworks amid the fire risk.
France’s weather service says the heat episode will last at least until the middle of next week, with only a first easing along the Atlantic slope in the early part of the week. In other words, the Île-de-France region remains under a heatwave for several more days. The pattern is also widening: the red alert kicks off this Sunday at noon across thirteen additional departments, from Yonne to Aveyron, including Dordogne and Tarn. We lay out the latest trends in our piece on the end of the intense heat in Paris and Île-de-France.
The reflexes are unchanged: drink regularly to stave off thirst, close shutters and windows during the day, ventilate at night, avoid strenuous activity between 12:00 and 18:00, and check in on the elderly or anyone isolated in your circle. If you feel unwell, dial 15. The City of Paris has activated its heatwave plan, with cooling hubs, water points, and heightened monitoring, while the Île-de-France prefecture is relaying the departmental guidance. We’ve also noted Parisian parks open all night to let you breathe, a welcome breath of fresh air when the apartment stays warm long after sunset.
