Southern France Faces Heightened Heatwave and Fire Risks Amid Severe Drought

A fierce heatwave is currently intensifying in southern France, with temperatures expected to reach as high as 39 °C by the weekend. Météo-France has issued an orange alert for forest fire risks, especially in the Aude department, as drought conditions have left vegetation extremely vulnerable to ignition. By early next week, the heat is predicted to peak, potentially affecting regions even north of the Loire River.

As the heat expands to the southern regions, the Mediterranean departments are on high alert due to a combination of humidity levels dropping to 25-35% and the anticipatory heatwave forecast. The latest updates indicate that Thursday will usher in further temperature increases, exceeding 35 °C in various areas, particularly in the South-West. Additionally, while isolated thunderstorms may occur in the Alps and Pyrénées, the overall weather pattern remains dry and sunny.

Regarding drought conditions, since June 2025, France has witnessed a surge in water usage restrictions aimed at combating extreme dryness. Departments such as Pyrénées-Orientales, Loiret, Indre, Ardennes, and Ain are already experiencing crisis-level water shortages. Consequently, regional prefectures have implemented numerous decrees that could restrict access to drinking water as well as to surface and groundwater sources. The Ministry of Ecological Transition has launched a drought guide outlining four alert levels to assist authorities in managing water consumption effectively.

In summary, the combination of a stifling heatwave and increasing drought restrictions presents significant challenges for southern France, raising concerns about public health and the risk of forest fires as meteorological conditions develop over the coming days.
