Press release June 23rd, 2022 Finnish Environment Institute SYKE
The number of cyanobacterial observations in inland waters has increased slightly since last week. In sea areas, the cool water is keeping the amount of blue green algae relatively low for the time being. The warm weather forecast for Midsummer is likely to increase the number of cyanobacterial blooms in the coming weeks. The situation is typical for this time of year, although in some places, there have been more cyanobacterial observations than usual.
