France Faces Exceptional Heatwave with Red Alert in Seine-et-Marne

France is currently bracing for an exceptional heatwave starting June 21, 2026, with the Seine-et-Marne department placed under a red alert by Météo-France at noon. This intense heatwave is expected to rival the historical heat episodes of July 2019 and August 2003 in severity, although its exact duration remains uncertain.

According to Météo-France, the heat intensity will escalate over the weekend and may persist into the following week, affecting several regions across the country. Detailed temperature forecasts by region have been published, allowing residents to monitor and prepare appropriately.

In response to the crisis, the Departmental Operational Centre for crisis management in Seine-et-Marne has been activated to coordinate emergency measures and public safety efforts. Authorities advise the public to take protective actions including staying cool, drinking plenty of water, avoiding alcohol, ensuring sufficient food intake, and maintaining ventilation by closing shutters during the day and airing out at night.

Special attention is urged towards vulnerable populations such as the elderly and isolated individuals, with recommendations to check on them regularly. In cases of heat-related distress, individuals are encouraged to call emergency services at 15. Additionally, a dedicated hotline, the Canicule Info Service, is available from Monday to Saturday, 9 AM to 7 PM, at 0800 06 66 66 to provide guidance and support on heat protection.

This early and intense heat episode underscores the importance of readiness and vigilance as France faces what could be one of its most severe summer heatwaves in recent memory.
