Bathing waters in Northern Ireland
One of our responsibilities is to ensure our coastal waters are of high enough quality for the general public to bathe in. Water Quality Inspectors collect the water samples on our behalf. The samples are then analysed by the Water Management Unit based in Lisburn.
The bathing season runs from June through to mid-September during which water quality will be assessed on 20 different occasions. Bathing Water Quality information is updated weekly during the bathing season and displayed in the format of colour-coded posters. These posters are displayed on this page. These posters are circulated to all beach operators for public display.
