Cyanobacterial blooms on wane in sea, lakes

Windy and cloudy weather has restrained the occurrence of cyanobacterial blooms in the Finnish sea areas and lakes, said the Finnish Environment Institute (SYKE) in a press release.

However, according to the national algae monitoring, surface blooms of cyanobacteria may again become more abundant, once the weather warms and winds subside.

Consequently, future weather conditions will determine the algal situation for the rest of the summer.

In the Järvi-meriwiki maintained by the SYKE, everyone has the opportunity to establish their own observation site and share algal bloom observations from lakes and coastal areas.

Individual observations can also be sent while navigating different water bodies.

Municipalities and cities monitor the cyanobacterial situation on the beaches. So it is advisable to report rich cyanobacterial blooms on beaches to the health authorities of the municipality in question.

The cyanobacterial map presented on this algal bloom observations page combines the observations reported to the Järvi-meriwiki and from the beaches of the City of Helsinki as well as the observations based on satellite interpretations of the SYKE during the last three days.
