Europe Watch brings official European bathing-water data together in a simple guide for travellers. Water quality classifications are from the European Environment Agency under the Bathing Water Directive, licensed CC BY 4.0. Weather and sea temperature from Open-Meteo.

A classification covers four bathing seasons and is not a live safety assessment. It does not reflect short-term pollution after heavy rainfall. For results during the season, check the national authority linked on each page.
