Freezing of the Bothnian Sea started with the frosts, but there is only weak ice near the shore

The lights of Oulu and the bridges are reflected in the sea.
In Oulu, there is not much ice yet, especially in the Oulu River estuary, but there is already a thin layer of ice in the shallowest bays at sea. This picture was taken exactly one year ago in Oulu in November.

The first ice on the Finnish coast has formed in the innermost bays of the northern part of the Bothnian Sea, off Tornio and Kemi. Off Oulu, thin ice is present in shallow, sheltered bays.

The first sea ice maps of the winter have been published. There is thin ice in the bays at the bottom of the Bothnian Sea, although the water is about one degree warmer than in normal winters.

The sea ice is almost on a normal schedule, as the first ice is usually observed in the second or third week of November in the Bothnian Sea.
