Swimming in natural waters is very enjoyable. It is good for the body and soul. There are more than 30 beaches in the Espoo and Kirkkonummi region, offering a perfect setting for fun-filled summer days.

The samples are analysed for faecal bacteria. At the same time, the presence of blue-green algae is examined. In addition to sampling, Espoo Region Environmental Health Services conducts inspections at the beaches. The results of the water samples and information on the blue-green algae situation can be found at: espoo.fi/en/housing-and-building/environmental-health-services/bathing-water-monitoring. Information on bathing water temperatures and the presence of blue-green algae is updated on the ulkoliikunta.fi/en(external link, opens in a new window) website, where it will be available for 24 hours. 

Blue-green algae is often present at some beaches in Espoo and Kirkkonummi. The algae can be harmful to health. Young children especially should not swim in the water if blue-green algae is present. Some blue-green algae may produce liver toxins or neurotoxins. Blue-green algae may also cause nausea and eye, nose or lung symptoms. The blue-green algae situation at a beach may change rapidly, so it is important to visually assess the situation before entering the water. Here are two tips for identifying blue-green algae: 

  • Stick test: Take a stick and try to pick up some algae. If the algae hangs from your stick, it is not blue-green algae. If the algae disintegrates into particles, it usually is blue-green algae. 

  • Glass test: Take some bathing water into a glass and let it sit for a while. If green particles appear on the surface of the water, it is blue-green algae. 

It is important to observe good hygiene at the beach, as swimmers’ behaviour has a significant impact on water quality. Please follow these instructions to help maintain the good quality of bathing water. 

  • Only visit the beach in good health. 

    • If you have been ill with diarrhoea or vomiting, you should avoid swimming for approximately two weeks. 

  • Take care of hygiene. 

  • Use the showers and toilets available at the beach. 

  • Do not change your baby’s diaper in the bathing water. 

  • Do not swallow bathing water.
