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 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...	2022-08-25
Cyanobacterial observations still higher than average, warm and calm weather may further increase surface blooms in late summer 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....	2022-08-18
Warm weather has increased the number of cyanobacterial observations at sea and in inland waters 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 tempera...	2022-08-11
The cyanobacterial situation in lakes and at sea is calm, but warm weather may increase the number of blooms in late summer The cyanobacterial situation in lakes has deteriorated in some places since last week, although the national situation in lakes remains calm. In sea areas, the number of surface blooms has decreased, ...	2022-08-04
The poor cyanobacterial situation at sea has improved somewhat, small amounts of cyanobacteria in lakes The cyanobacterial situation has improved slightly since last week. The number of cyanobacterial observations in lakes has diminished as a result of the windy and rainy weather, and the poor cyanobact...	2022-07-28
Still abundant cyanobacteria in sea areas, situation in lakes better than normal There are now cyanobacterial occurrences in all sea areas. Abundant cyanobacteria have been observed especially in the coastal areas of the Archipelago Sea and the Gulf of Finland. The situation in la...	2022-07-21
The cyanobacterial situation has deteriorated considerably in sea areas, stable situation in lakes There has been a sharp increase in cyanobacterial observations both on the coast and in the open sea. Observations have increased in both the Gulf of Finland and the Gulf of Bothnia. The cyanobacteria...	2022-07-14
The cyanobacterial situation has remained fairly stable in lakes and sea areas The number of cyanobacterial observations in lakes has remained stable or even diminished as a result of the cooler weather, and the situation in inland waters is now slightly better than on average. ...	2022-07-07
Hot weather has increased the number of cyanobacterial observations in sea areas, situation in lakes remains stable As a result of the hot weather, water bodies have become warmer, which has led to an increase in cyanobacterial observations in sea areas. Cyanobacterial observations have become more common, especial...	2022-06-30
The number of cyanobacterial observations in lakes has increased during the Midsummer week, situation at sea remains calm The number of cyanobacterial observations in inland waters has increased slightly since last week. In sea areas, the cool water is keeping the amount of blue green algae relatively low for the time be...	2022-06-23
Cyanobacterial observations have slightly increased in lakes and at sea Some cyanobacterial observations have been made in Finnish inland waters and sea areas, but the situation is typically calm for the early summer. At sea, cyanobacteria have been observed in sub-surfac...	2022-06-16
The cyanobacterial situation is still calm in Finnish lakes and sea areas In Finnish lakes and sea areas, no significant cyanobacterial observations have been made so far. The cool weather in early summer has not been conducive to the development of cyanobacterial blooms. I...	2022-06-09
The cyanobacterial situation is calm – no cyanobacterial observations in lakes or sea area The Finnish Environment Institute (SYKE) has started reporting observations of summer 2022 cyanobacterial blooms this week. No cyanobacterial observations have yet been made in Finnish sea areas or in...	2022-06-02
Summary of algal bloom monitoring June-August 2021: The hot weather boosted the growth of cyanobacteria in the early summer – still the amount of cyanobacterial blooms was below average since mid-July During the summer, the cyanobacterial situation has varied in both Finnish lakes and sea areas. The amount of cyanobacteria was exceptionally at its peak in the sea areas already in mid-July. Even in ...	2021-08-30
The cyanobacterial situation is calm in lakes and sea areas The amounts of blue-green algae in lakes and coastal areas are still smaller than average. Only in some areas of the Archipelago Sea have abundant cyanobacteria been observed in coastal areas. As is t...	2021-08-19
Moderate amounts of cyanobacteria in lakes and coastal areas, increased observations in open sea areas of the Gulf of Finland The cyanobacterial situation har remained calm in lakes and coastal areas. The amounts of cyanobacteria in inland waters are small compared with the average. In the open sea areas of the Gulf of Finla...	2021-08-12
The cyanobacterial situation has calmed down both in inland waters and sea areas The number of cyanobacterial observations has started to decline in inland waters and on the coasts of the Baltic Sea. The situation in inland waters is calmer than usual. Usually, August is the month...	2021-08-05
Cyanobacterial observations have increased in both lakes and sea areas; the situation is typical for the late summer Larger amounts of cyanobacteria have been observed in inland waters than in the previous week. The observations are concentrated in eutrophic lakes and bays in the southern parts of Finland. Cyanobact...	2021-07-29
The cyanobacterial situation has calmed down, small amounts of cyanobacteria in lakes and sea areas The cyanobacterial situation has calmed down both in inland waters and sea areas. Almost all cyanobacterial observations concern small amounts of cyanobacteria. In lakes, storm Riikka stirred up the s...	2021-07-22
Widespread cyanobacteria in the open areas of the Bothnian Sea, the warm weather has contributed to the growth of cyanobacteria in lakes Along the coast and in the open sea areas varying amounts of cyanobacteria have been observed. On the coast, observations continue to centre around the Archipelago Sea. The hot weather has contribute...	2021-07-15
