Potsdam sits in northern or eastern Germany on the North German Plain, where a temperate maritime-to-continental climate spreads rain fairly evenly across the year, with the heaviest short-term totals usually arriving in summer thunderstorms rather than a single wet season.
Just southwest of Berlin among a chain of lakes, the city’s many waterways mean local flood risk is tied closely to lake and river levels rather than the sea. Because the terrain here is generally flatter than in the south and west, flooding is more often driven by a river’s slow rise over days than a sudden flash flood, but intense convective storms can still overwhelm local drainage quickly, which is where radar proves useful. The Deutscher Wetterdienst (German Weather Service) operates the national radar network. Learn more: Flash Flood Warning Signs on Radar · Open the full Rain Map
