Cool and windy weather has tempered cyanobacterial blooms. In lakes, the number of observed cyanobacterial blooms has even decreased since last week. Cyanobacteria are mixed in the water column in the open sea areas, especially in the western Gulf of Finland and the northern Baltic Proper. In windless situation, surface blooms may build up quickly.
