France faces hotter summer and wetter autumn in 2026

Météo France’s three‑month outlook for August 2026 predicts a markedly warm month across metropolitan France, with average temperatures about +2 °C above normal and a high probability of heat‑related warnings. Precipitation is expected to stay close to seasonal averages, though some regions such as the northwest and the Mediterranean coast may see modestly higher rainfall and localized thunderstorms.

For the September‑October quarter, both Météo France and MeteoNews forecast a shift toward wetter conditions. Rainfall is likely to be above normal, especially around the Mediterranean, the western and southern parts of the country, and the northeast, with the potential for intense Mediterranean rain events. Temperatures are projected to be slightly above normal in the east (+1 °C) and near normal elsewhere, while sunshine is expected to be reduced throughout the season.
