Welcome to the Baltic Sea Ice Services
The Bay of Bothnia is covered by mostly 15-50 cm thick, very close ice, with new ice or level ice covered lead between Malören over Nordströmsgrund along the Swedish coast up to Holmögadd. In the Sea of Bothnia the ice has drifted towards the east into the central Sea of Bothnia. The Gulf of Finland is mostly covered by new ice and level ice and in the north and east by very close ice and fast ice. In the Gulf of Riga there is mostly close to very close ice and level ice. Further south ice is present only in some sheltered areas.
