The heatwave keeps Île-de-France under red alert: Météo-France confirms the red warning for the eight departments of the Paris region this Monday, July 13, and Tuesday, July 14, 2026, with temperatures set to rise again for Bastille Day. Here’s the latest.
The red heatwave alert remains in effect in Paris (75) and in the seven other departments of the region: 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 issued this Monday, July 13, 2026 at 6:49 a.m., Météo-France warns of a severe, prolonged heatwave, set amid an unusually hot air mass. Forecasts hold steady, unsurprising: the heat is expected to persist at least until midweek.
By 5 a.m., the thermometer already read 24°C in Paris-Montsouris. The same pattern in the outer Paris region, with 23.5°C in Orly and Courdimanche, 23.5°C in Saint-Cyr-l'École, 23°C in Fontainebleau, and 22°C in Melun, Magnanville and Roissy.
That's exactly what justifies the red alert: when the night no longer dips below 22 or 24°C, the body doesn't recover and fatigue builds up day after day, even among healthy people.
This afternoon, conditions ease slightly without a major shift in the overall pattern. A somewhat thicker cloud cover and a low risk of rain and thunderstorms are expected across a broad western and northern portion of the region, pushing the températures maximales down by 1 to 3°C compared with yesterday.
That thunderstorm risk has earned the region a second alert level: Météo-France also places the eight Île-de-France departments under yellow thunderstorm vigilance for Monday, July 13. Not alarming, but worth watching the sky late in the day, with heavy downpours over a dry, sun-baked ground.
The lull will be short. Tuesday, July 14, 2026, National Day, the early-morning lows still hover between 18 and 24°C depending on the area, with 21 to 23°C in the capital and its inner suburbs.
In the afternoon, the highs rise decisively: 35–37°C in Paris and the inner suburbs, 35–38°C in Seine-et-Marne, 35–36°C in Essonne, and 34–36°C in the Yvelines and Val-d'Oise. Needless to say, the parade and festivities will unfold under blistering heat. We’re tracking the latest developments in our article on the end of the strong heat in Paris and Île-de-France.
The heat isn’t just pushing the thermometer higher. In Seine-et-Marne (77), a fire that broke out Sunday afternoon on the edge of the A6, in the town of Noisy-sur-École, has already scorched around 800 hectares in the western part of the Fontainebleau forest. Authorities describe the blaze as exceptionally large, the kind of scale never seen before in the forested heart of Île-de-France.
Four hundred firefighters worked through the night, and for the first time in Île-de-France, water-bombing aircraft (two Dash, supported by helicopters) were sent from the south of France. The blaze is not yet under control, and rescuers expect to be engaged for one to two weeks. About fifteen homes were evacuated in Le Vaudoué and Achères-la-Forêt, while the A6 remains closed in both directions for around twenty kilometers, between Soisy-sur-École and Nemours. The préfecture de Seine-et-Marne publishes regular situation updates and asks residents to stay indoors to avoid smoke.
On the ground, the plume is visible from twenty kilometers away. That means hikes in the massif, normally one of the Franciliens’ few breaths of fresh air, will have to be put on hold for a while.
The fire risk has already forced a large part of the festivities to be canceled. Several prefectures have issued bans, as detailed in our outlook on Essonne, Yvelines, Val-d'Oise and Seine-et-Marne. Before you set out, it’s worth checking the list of fireworks canceled in Île-de-France on July 13 and 14, updated as new announcements come in.
In Paris, the police prefecture has also canceled the firefighters’ balls on July 13 and 14 at the barracks, as well as outdoor sports events or those held in non-air-conditioned venues. National Day 2026 is certainly taking on very unusual proportions in the capital.
The same precautions still apply: drink water regularly without waiting for thirst, close shutters and windows during the day, ventilate at night, avoid strenuous activity between noon and 6 p.m., and check in on nearby elderly or isolated residents. If you feel unwell, call 15.
The City of Paris has activated its heatwave plan, with water stations, cooling "islands" and heightened monitoring, while the Île-de-France prefecture is relaying guidelines department by department. On our end, we’ve identified cooling spots to beat the heat in the capital and Paris parks open all night to help you breathe, a real respite when the apartment stays hot well after sunset.
The Grandes Serres and the Menagerie at the Jardin des Plantes in Paris have been closed until the end of the alert.
