In the Bay of Bothnia, there is up to 70 cm thick fast ice in the northern archipelagos and up to 35cm thick fast ice in the southern part. At sea there is 20-45cm thick, very close ice in the north, further south there is level ice outside the coasts and 10-30cm thick, very close ice at sea. The Quark is mostly covered by very close and level ice and at the coast there is 15–40 cm thick fast ice. Along the coast of the Bothnian Sea, there is level ice and up to 35 cm thick fast ice, further out new ice in the west and close ice in the east and north. In the Gulf of Finland, there is 20–40 cm thick fast ice in the east and 10-35cm thick fast ice along the northern coast. The sea is covered by 5-25cm thick very close ice east of about 26°E, further west close ice and level ice in the north. The sea in the southwest is still ice free. The Gulf of Riga is covered by close ice and new ice, at the coast in the northeast there is 20-40cm thick fast ice or very close ice. Elsewhere in the Baltic region, new ice drifts outside the coast. In sheltered places like the Bodden¬waters around Rügen and the lagoons in the south and southeast there is fast ice as well as very close ice, partly thicker than 30 cm. New ice and very close ice is present in the Bay of Pommerania. Ice is present also in places along the North Sea coast.
