Ice Information


Welcome to the Baltic Sea Ice Services


The Bay of Bothnia is covered by fast ice, level ice and mostly very close ice as well as some new ice, except for the central part. Norra Kvarken is nearly completely covered by sea ice. Further south, there is fast ice, thin level ice and new ice mostly close to the coasts. At light frost in the southern regions and very strong frost in the northern regions, further sea ice will form.
