The amount of cyanobacteria has increased since last week, and it may continue to increase if the weather stays warm. Cyanobacteria are abundant especially in the Southern and South-Western Finnish sea areas. In lakes, the amount of cyanobacteria has increased clearly since last week, and now there are slightly more cyanobacterial observations from lakes than usually during this time of the summer. More in Finnish.

In addition to the national blue-green algal monitoring, the Finnish Environment Institute has today published an additional release about the Baltic Sea's blue-green algae situation.
