Finland - Weather

Mar 20, 2025

Part of the country lies north of the Arctic Circle, however, the influence of the Baltic Sea keeps the climate milder than other countries on the same latitude. The sailing season is limited to the summer when the winds are variable. The surrounding landmass affects the winds which can be light in summer.

The sea is frozen from December to March or early April (in the northern part of the Gulf of Bothnia to May). In southern Finland, the sailing season tends to be from April to October.

Turku Radio station broadcasts marine forecasts and navigational warnings in English on the free VHF working channels and MF working channel frequencies. The current weather report can be seen on the Finnish Meteorological Institute's website
