On Tuesday morning, the warnings issued by the health department on Monday are still in effect. The water in the Tri-City bathing areas is unsuitable for bathing due to the bloom of blue-green algae. These are beaches popular with tourists in Sopot, Gdynia and Gdańsk.

Almost every year, especially during the holiday season, bathing areas on the Baltic coast fall victim to blue-green algae. Factors that affect their bloom include: water temperature above 16-20 degrees Celsius (although blue-green algae blooms are known at lower temperatures), the presence of biogenic salts (especially phosphates), weak wind and no precipitation.

Data on the state of water and the safety of bathing are regularly provided on its website by the Chief Sanitary Inspectorate, which has developed a special map with a list of bathing areas, addresses and markers that help to familiarize yourself with dangerous places.

From data posted on the GIS website on Monday, July 10, approx. 12.00, shows that the water in these Pomeranian bathing areas is unsuitable for bathing due to cyanobacteria bloom: ● Gdynia Babie Doły, ● Gdynia Śródmieście, ● Gdynia Redłowo, ● Gdynia Orłowo, ● Sopot Kamienne Potok – Koliba, ● Sopot 13-17, ● Sopot Northern Park, ● Sopot K-22, ● Sopot Łazienki Południowe I, ● Sopot Łazienki Południowe II, ● Sopot Kamienne Potok, ● Sopot 32A-33, ● Gdańsk Jelitkowo, ● Gdańsk Piastowska Jelitkowo, ● Pier Gdańsk Brzeźno, ● Hallera Gdańsk Brzeźno , ● Dom Zdrojowy Gdańsk Brzeźno.

What are cyanobacteria and what can they cause?

Blue-green algae (cyanobacteria) are among the oldest organisms on earth. They occur in both salty and inland waters, floating freely in the water depths. During windless weather, some blue-green algae may rise to the surface of the water and form scum there. They then look like spilled paint, jelly or flakes floating on the surface of the water.

In the case of blue-green algae blooms resting by the water, an absolute ban on entering it is recommended. Bathing in cyanobacteria-contaminated water can cause adverse reactions of the body: from skin rashes to redness of the conjunctiva. Gastrointestinal complaints including diarrhoea, vomiting and abdominal pain may occur if such water is swallowed.

health department recommends caution and distinguish cyanobacteria from macroalgae, which may also appear in the coastal zone of the Baltic Sea. Often, the waves throw these green mats on the shores of the beaches, which can look unsightly and give off an unpleasant smell after bacterial decomposition. Unlike cyanobacteria, however, they are not harmful and do not produce toxins.
