In the Bay of Bothnia, there is rotten fast ice along the coasts in the northwest and north. At sea in the central part, there is close to very close, 10–50 cm thick and in places ridged ice. Open water with some thicker floes surrounds the ice down to about Kokkola and Nygrån. Further south it is ice-free.
