Météo-France has placed 72 departments under a red-level heat-wave alert for Thursday, June 25, 2026 [1].

This action represents a record for the country, signaling an extreme public health risk as an intense heat wave, or canicule, sweeps across the region. The scale of the alert indicates a level of environmental stress that exceeds previous historical norms for the month of June.

The national weather agency said the forecast for Thursday is "suffocating" [1]. To reach the current total of 72 departments in red vigilance, Météo-France added 14 new departments to the highest alert level [2]. This follows a Wednesday where 58 departments were already under red vigilance [3].

While the majority of the country faces the highest alert level, 17 departments remain under orange vigilance [4]. These areas, including Vaucluse and Bouches-du-Rhône, still face significant heat risks, but have not yet reached the critical threshold required for a red alert [4].

Local authorities are monitoring the situation as the heat wave intensifies. Météo-France said the current situation is "du jamais vu dans le pays," or something never before seen in the country [3]. The agency's warnings emphasize the necessity of immediate precautions to prevent heat-related illnesses and deaths during this peak period.

The red-level alert is the highest tier of the French weather warning system. It triggers specific government protocols to protect vulnerable populations, including the elderly and those with chronic illnesses, while urging the general public to limit outdoor activity during peak temperature hours.

“Météo-France prévoit un jeudi « suffocant »”

The unprecedented expansion of red-level alerts to 72 departments suggests that France's existing heat-wave infrastructure is being tested by increasingly extreme weather patterns. By labeling this event as 'never before seen,' Météo-France is highlighting a shift in climatic baselines where record-breaking heat is occurring earlier in the summer season than historically expected.
