Mulhouse sits in eastern France under a semi-continental climate, with colder winters than the rest of the country and a summer rainy season shaped by convective thunderstorms rather than a single wet period.
Near the Rhine in Alsace, the city’s proximity to the Vosges mountains means runoff can reach local streams quickly. Because summer storms here can be locally intense even when the season’s overall rainfall is unremarkable, radar is a useful way to spot a fast-developing storm cell before it arrives. Meteo-France operates the national radar network. Learn more: Flash Flood Warning Signs on Radar · Open the full Rain Map
