France swelters under unprecedented May heatwave: seven dead, emergency calls surge, and eight departments on orange alert

Record-breaking temperatures

France is experiencing what Météo-France has described as an "unprecedented heatwave episode for the month of May in the west of the country." On Monday, 25 May 2026, the country recorded its hottest May day since measurements began. Temperatures have consistently exceeded 35°C in the shade, with the Sarthe department reaching 33°C on Whit Monday alone. The heat is expected to persist, with another 35°C forecast for Tuesday 26 May.

Human toll and emergency response

At least seven deaths have been linked directly or indirectly to the extreme weather, according to Ouest France. The strain on health services is intensifying. BFMTV reports that emergency call centres have seen dramatic increases in activity since 22 May. In the Manche department, calls surged by 30% and medical regulation cases rose by 20%. Rennes recorded 2,450 calls on Monday 25 May, compared to a typical 1,800 for a Monday in the same period—a 30% jump—alongside a 20% increase in emergency department visits. In the Paris region, the Val-d'Oise saw a 15% rise in emergency calls over the weekend of 23–24 May, while the Assistance Publique – Hôpitaux de Paris noted a 7% weekly increase in calls.

Orange alert across the west

Météo-France placed eight western departments under an orange heatwave alert on the afternoon of Monday 25 May: Finistère, Morbihan, Vendée, Ille-et-Vilaine, Manche, Mayenne, Maine-et-Loire, and Loire-Atlantique. The alert remains in effect as temperatures continue to climb. Ouest France also notes that a storm warning is in place for some of these areas.

Government mobilisation

Sébastien Lecornu is set to chair an inter-ministerial meeting on Thursday to review the preparedness of state services in the face of this exceptional heat event, Le Figaro reports. The meeting will address the ongoing response and coordination among government agencies.

Workers' rights in extreme heat

With temperatures surpassing 35°C, questions are being raised about workplace safety. Le Monde republished a 2023 article outlining French labour law regarding heatwaves, noting that employees have the right to stop work if their employer fails to provide adequate protections such as fresh water, ventilated premises, or adjusted working hours.
