Monitoring is organised jointly by the Centres for Economic Development, Transport and the Environment, municipal environmental officials and the Finnish Environment Institute (Syke).Cyanobacterial reviews summer 2023 (sttinfo.fi) Blue-green algae situation has calmed down at sea and in lakes 2023-08-31 Reduced wind increases surface blooms of blue-green algae 2023-08-24 Blue-green algae situation has remained stable both in lakes and at sea 2023-08-17 Strong winds have dispersed blue-green algae surface blooms in inland waters and at sea 2023-08-10 Unstable weather has kept the blue-green algae situation calm in lakes, surface blooms observed at sea 2023-08-03 The blue-green algae situation has deteriorated in marine areas and inland waters 2023-07-27 Windy weather has restrained blue-green algae blooms 2023-07-20 Warm weather has increased the number of blue-green algae observations in inland waters and sea areas 2023-07-13 Cool and rainy weather has kept the blue-green algae situation calm on lakes and at sea 2023-07-06 The blue-green algae situation has deteriorated significantly in inland waters and coastal areas, also abundant blue-green algae in sea areas 2023-06-29 Blue-green algae observations increased in inland waters and at sea during Midsummer week 2023-06-22 Blue-green algae observations increased slightly in inland waters and coastal areas 2023-06-15 The blue-green algae situation calm both in the Baltic Sea and in lakes 2023-06-08 Summer algae forecast: Warm and calm weather conditions can lead to powerful blooms of blue-green algae in the Baltic Sea 2023-06-01 Cyanobacterial reviews 2018–2023 Summary of the national cyanobacteria review June–August 2022: Abundant cyanobacteria observed at sea this summer, cyanobacterial situation in lakes remained at the level of recent years 2022-08-25 The cyanobacterial situation in the past summer has varied according to changing weather conditions. Cyanobacterial levels in sea areas and lakes peaked during the hottest periods of the summer in mid-July and mid-August. The cooler weather in late July and early August curbed the growth of cyanobacterial blooms for a while. In lakes, this summer’s cyanobacterial situation remained quite typical compared to previous years. Cyanobacterial observations still higher than average, warm and calm weather may further increase surface blooms in late summer 2022-08-18 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. Warm weather has increased the number of cyanobacterial observations at sea and in inland waters 2022-08-11 The cyanobacterial situation has deteriorated from previous weeks due to warm weather. Cyanobacterial blooms have now been observed more than average in inland waters, even though lake surface temperatures are typical for the season. Large cyanobacterial blooms have also been observed in some sea areas. If the weather stays calm and warm, it is likely to increase the number of cyanobacterial blooms.
