Tallinn, Estonia’s capital on the Gulf of Finland, receives around 650 mm (about 26 inches) of rain a year, with a fairly even seasonal spread and a modest late-summer peak from convective showers. Its coastal position exposes it to Baltic Sea weather systems, though it’s generally more sheltered than cities facing the open Atlantic further west. Short, sharp summer downpours are the main source of sudden heavy rainfall, occasionally causing localized flooding in the historic old town’s narrow streets. Because Baltic weather here can shift quickly on a summer afternoon, radar remains a useful practical tool. Estonia’s Environment Agency operates the national radar network.
