Welcome to the Baltic Sea Ice Services
In the Bay of Bothnia, there is rotten fast ice in places in the archipelagos north of 65°25’N and east of Luleå. Off the fast ice there are smaller areas of very close ice and single drifting ice floes further out. Outside the Finnish coast between Nahkiainen and Kokkola, there is 10–40 cm thick, very open to close ice. Outside the ice edge, there is open water; else, it is ice-free at sea.
