Blue-green algae season begins quietly across Finland

This week, Finland saw a subdued start to the blue-green algae (cyanobacteria) season, with only modest blooms in inland and coastal waters, and none offshore, according to the Finnish Environment Institute (Syke).

Over the past week, only two inland observation sites recorded abundant algae levels, while around 15 other sites reported moderate occurrences. Most sightings occurred in Southern Finland, with a few in Central Finland and a single sighting in southern Lapland. Syke maintains 246 active inland monitoring stations.
