After several days of maximum alert, the heatwave is loosening its grip on Paris and the Île-de-France. Météo-France keeps the orange heat alert in effect this Thursday, July 16, 2026 across the 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), ahead of a planned easing later in the day.
According to the bulletin issued this Thursday at 6:10 a.m., the orange alert is lifted this Thursday at 10 p.m. and will give way to yellow, before a return to green confirmed starting tomorrow Friday 17 July at 6 a.m. The institute still warns of a severe, enduring heatwave, but the very hot air mass that had been stagnating over the country is retreating. Friday’s high temperatures are expected to fall below 30°C: the long-awaited relief, after days of anticipation, is finally taking shape.
The morning is mild, not chilly. This Thursday at 5:30 a.m., Météo-France reports 21.6°C at Paris-Montsouris, 17.6°C in Melun and 16.9°C in Meaux (77), 19.6°C in Magnanville (78), 20.3°C at Roissy and 17.8°C in Pontoise (95).
For the afternoon, the expected high temperatures range from 32 to 34°C across the region. Thursday night into Friday finally signals a turning point, with cooler lows between 15 and 20°C depending on the area — a sign of a more comfortable night after a prolonged spell of tropical nights.
A switch to milder temperatures comes with stormy conditions that could stretch across several days. Météo-France has placed about fifteen departments in orange alert for storms in the center and east of the country (Île-de-France not included for now), but warns the alert could be widened later in the day.
The first storms develop in the early afternoon and then strengthen, with gusts of 80 to 100 km/h (occasionally 110 to 120 km/h in some spots), sometimes large hail, heavy rain and sustained lightning activity. In Île-de-France, we’re keeping an eye on the sky as the yellow alert remains in force on Friday as well.
As long as the orange alert remains in effect, caution is advised for vulnerable groups: the frail, the elderly, infants, pregnant women, and workers exposed to heat. The recommended precautions stay the same: drink regularly even before you feel thirsty, keep your home sealed and shutters drawn during the day, ventilate at night, and check in on isolated relatives or neighbors.
The official map can be consulted on Météo-France Vigilance and the detailed forecasts on meteofrance.com, while the Canicule info service is reachable at 0 800 06 66 66 (toll-free) and the ARS Île-de-France as well as Santé publique France are relaying the official guidance. In Paris, the cooling havens, parks, churches and air‑conditioned museums remain particularly useful on this final, tense day.
The region is emerging from a particularly punishing spell, with water restrictions, a forest fire in the Fontainebleau forest and severely strained transport. This Thursday marks a turning point: the heat wave is easing, storms are taking over and the return to more normal conditions for the weekend is being confirmed. We breathe, cautiously.
