The figure shows the share of bathing water quality classes by type and bathing season.
Assessments are based on the two microbiological parameters specified in the BWD: E. coli and intestinal enterococci. In 2025, EU Member States reported 14,748 coastal waters and 7,262 inland waters. This distribution is consistent with previous years, with approximately two-thirds of bathing waters being coastal and one-third inland. More detailed country-level information is provided in Annex 1.
Percentage
Data extraction from EEA CWS wigeon MSSQL server (BWD_Production.assessmentResults.statusOverview).

Non-EU Member States (CH, AL, ME and UK) have been filtered out from this data extract as well as bathing waters classified as "0 - Missing data".
