A heatwave is affecting Brittany, France, in late May 2026, with temperatures expected to reach record levels for the month. According to Météo Bretagne, a heat dome caused by high atmospheric pressure is responsible for the intense heat.
Météo France has issued orange heatwave alerts for several departments in the region. Temperatures are forecast to exceed 35°C in some areas, breaking previous May records. The heatwave is expected to last several days.
Local authorities have advised residents to stay hydrated, avoid outdoor activities during peak heat hours, and check on vulnerable individuals. The situation is being closely monitored as the heatwave continues.
