Significant risk of blue-green algae blooms in summer across Finnish sea areas – warm and sunny summer may dramatically increase occurrence of blooms
2019-06-06
The risk of significant and widespread blue-green algae blooms in Finnish sea areas matches that of previous years, since the nutrient situation has remained largely the same. This summer brings with it a substantial risk of blue-green algae formations in the Gulf of Finland, the northern part of the Baltic Proper and most of the Finnish Archipelago Sea. The weather conditions will determine whether or not the risk is realised.

The risk of significant blue-green algae blooms in summer 2018 is lower than earlier years in Finnish marine areas
2018-06-07
The risk of widespread blue-green algae blooms in Finnish sea areas is less than during the last two years, because the algae have less nutrients available in comparison to previous years. However, significant algae blooms may form in the Gulf of Finland if the summer is warm. A warm May could cause blooms to occur earlier than normal this year.

Significant blue-green algae blooms possible in Finnish marine areas during 2017 summer
2017-06-01
The risk for vast blue-green algae blooms in the Gulf of Finland is greater than during previous years. The exceptional nutritional conditions are caused partially by major Baltic inflows from the North Sea in 2014 and 2016, which allowed the phosphorous deepwater to reach the Gulf of Finland. In addition, the lack of winter ice and the windy winter mixed the water layers and brought nutrition to the surface layer of the Gulf of Finland.

Algae prognosis: low or moderate risk of blue-green algal blooms in Finland's sea areas
2013-06-06
According to the algae prognosis of the Finnish Environment Institute’s Marine Research Centre, the risk of blue-green algal blooms in Finland's sea areas is mainly low this summer. In the western Gulf of Finland, the southern reaches of the Archipelago Sea, and in the north-eastern parts of the Baltic proper, there is a moderate risk of algal blooms. No major blooms are forecast in the Gulf of Bothnia. The southern Baltic Sea faces the greatest risk of blue-green algal blooms.
