The yellow color of the water in the Baltic Sea has worried holidaymakers who are going to Mrzeżyno in the West Pomeranian Voivodeship. In an e-mail to the editorial office of tvnmeteo.pl, Dr. hab. Mirosław Darecki explained that there was no reason to worry because the yellow sediment was simply pine pollen.
Footage from the beach in Mrzeżyno began circulating on social media, showing the unusual color of the water in the Baltic Sea. Fortunately, yellow waves are not the result of pollution or other unfavorable health phenomena. It’s just pine pollen, blown in by the wind. As explained by Mirosław Darecki, Ph.D., from the Institute of Oceanology of the Polish Academy of Sciences, such pollen may also be washed into the sea from the ground.
“It is highly probable that the sediment recorded in the film is pine pollen. This is a typical phenomenon at this time of year at sea in the coastal zone, this year it takes place a little later than usual, but the entire vegetation is delayed,” the scientist noted.
When does pine dust?
Fortunately, pine pollen is quite tolerable for allergy sufferers. The most popular variety in our country, Pinus sylvestris (Scots pine), usually produces pollen from the beginning of May to mid-June. A characteristic yellow precipitate is then formed, which, although harmless, can be bothersome when it settles on car surfaces, windowsills or garden furniture.
