Copenhagen receives around 600 mm (about 24 inches) of rain a year, fairly evenly spread across the seasons, though summer thunderstorms have become an increasingly prominent concern for the low-lying Danish capital in recent years.

Because these short, extremely intense summer storms remain the city’s single biggest weather-related risk, radar tracking is treated as a genuinely critical real-time tool by both residents and city planners. Denmark’s Meteorological Institute, DMI, operates the national radar network.
