Cyanobacterial observations still higher than average and warm and calm weather may further increase surface blooms in late summer, said the Finnish Environment Institute (SYKE) in a press release on Thursday.

The number of cyanobacterial observations has remained stable throughout Finland.

As a result of warm weather, lakes are slightly warmer than average, which helps maintain the growth of cyanobacteria.

In sea areas, the amounts of cyanobacteria are still higher than the long-term average, but wind has caused the cyanobacteria to mix with water.

Calm and warm weather, as well as strong showers, can increase the number of cyanobacterial surface blooms in late summer.
