Ice conditions in the Baltic Sea
Ice conditions in the Baltic Sea vary a lot from one year to another. The maximum ice covered area varies between 52 000 and 422 000 square kilometres, which stands for 12-100 per cent of the total Baltic Sea area (including Kattegatt and Skagerrak). On average the sea ice covers 218 000 square kilometres every winter. The maximum ice cover is normally reached in late February or in March.
