France Faces Widespread Red Heatwave Alerts with Extensive Public Safety Measures

On June 21, 2026, a severe heatwave prompted Météo-France to place 35 French departments under red vigilance, signaling the highest level of heat alert. Temperatures are forecasted to soar between 38 and 41°C, with some regions, such as Vendée, Gers, Yvelines, and Seine-et-Marne, expecting daytime highs near or exceeding 39°C.

In Seine-et-Marne, starting at noon on June 21, authorities issued three immediate prefectural orders to protect public health. These include bans on public alcohol consumption during the Fête de la Musique and Saint-Jean celebrations, a total prohibition on fireworks due to fire risks, and the cancellation or postponement of outdoor sports unless relocated to air-conditioned venues. Residents have been urged to stay hydrated, avoid alcohol, eat properly, and maintain contact with vulnerable individuals. A dedicated helpline, Canicule info service, is available for advice.

Similarly, Vendée faces daytime temperatures around 40°C and nighttime lows reaching up to 30°C. The prefecture has banned public events such as sports and fireworks and prohibited alcohol consumption and sales in public spaces. While schools remain open, parents may opt to keep children at home. Emergency services have heightened readiness, and measures have been enacted to prevent forest fires. Special support for homeless individuals includes additional water distribution and shelter provisions.

Yvelines authorities anticipate temperatures up to 39°C by June 22-23. They have imposed a temporary ban on alcohol sales and consumption in public places, impacting events like the Fête de la Musique. Some events are canceled or moved indoors. While schools stay open, parents are encouraged to keep children at home if possible, and teleworking is advised. The Seine river swimming is banned due to strong currents, with bathing only permitted in designated areas. Forty new emergency accommodation spaces have opened for vulnerable people.

Gers also experiences intense heat, with predicted maximums near 39.5°C. Public outdoor events are banned from noon to 9 PM on June 21. Employers are instructed to reassess employee risk daily, considering work conditions and temperature. State services are mobilized to assist vulnerable populations under the ORSEC plan.

The heatwave has caused concern due to its potential health impacts, particularly among those aged 75 and over, with increased mortality rates noted in past similar events. Local authorities are empowered to implement event cancellations, alcohol bans, and protect workers' health. The Prime Minister emphasizes teleworking options and animal welfare during this period.

Overall, France faces an unprecedented summer heatwave with comprehensive regional preparations and strict public health measures to mitigate risks associated with extreme temperatures, fire danger, and vulnerable population welfare.
