Orange Heatwave Alerts Issued Across Multiple French Departments Starting August 11, 2026

Météo France has escalated the heatwave warnings to Orange level for several French departments as of August 11, 2026, highlighting rising health risks amid summer’s peak temperatures. The alert now affects half of France’s territory, including the departments of Vendée and La Manche.

In Vendée, where Orange vigilance starts at noon on August 11, temperatures are forecast to reach between 35 and 38°C inland, with coastal areas seeing highs from 32 to 35°C. The prefect has mobilized local mayors to implement safety measures and emergency plans aimed at protecting vulnerable groups such as the elderly, disabled, and those with chronic illnesses. The public is urged to stay hydrated, keep homes cool using misting devices, and avoid heat exposure, especially during the hottest hours. Employers are also advised to adapt work schedules to reduce outdoor heat exposure for workers.

Similarly, La Manche has been placed under an Orange heatwave alert starting the same day and time. Authorities recommend frequent water intake, maintaining homes cool by shutting shutters and windows during the day and airing out at night. Outdoor physical activity, including sports and gardening, should be limited, particularly during peak heat hours. Residents are also encouraged to check on vulnerable individuals regularly for signs of heat-related illness.

Both departments emphasize the critical need to recognize heatstroke symptoms – such as high fever, confusion, or loss of consciousness – and to contact emergency services immediately if these occur. The expansion of Orange vigilance covers 43 departments in western and southeastern France, pointing to a widespread and significant heatwave event. Citizens can track updates via Météo France’s website and social media channels.

This development builds on a broader trend as half of France faces extreme heat conditions, necessitating coordinated public health responses and individual protective actions to mitigate the risk of heat-related illnesses.
