Reims 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.
In the Champagne region, the city’s Vesle River responds to the area’s continental-influenced summer thunderstorms. 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
