Brussels sits at the heart of Belgium and receives around 850 mm (about 33 inches) of rain a year, spread fairly evenly across all seasons under the same rotating Atlantic weather systems that affect much of northwestern Europe. Rain here tends to be frequent but generally moderate, with the city seeing more overcast, drizzly days than dramatic downpours, though summer convective storms do occur and can bring localized flooding to specific low-lying streets. As the seat of the European Union’s main institutions, the city’s weather is watched closely by a genuinely international audience. Because conditions can shift within a single afternoon, radar remains a practical daily tool. Belgium’s Royal Meteorological Institute operates the national radar network.
