How bathing water classifications work
The four classes
Under the EU Bathing Water Directive (2006/7/EC), every designated bathing water is placed in one of four classes: Excellent, Good, Sufficient or Poor. The class is based on two groups of faecal indicator bacteria, Escherichia coli and intestinal enterococci, measured in water samples taken during the bathing season.
A class is assessed once a year and looks back over several seasons of samples, normally four. It therefore describes the long-term pattern at a site, not the water on a particular day.
What a class does not tell you
A class is not a real-time safety assessment and not a forecast. Short pollution events, algae, currents, weather and other hazards are outside its scope. Local signage and the competent authorities are the source for current conditions.
Other statuses
"Not classified" means there were not enough samples to assign a class. "Newly identified" means the site was added to the list recently; such a site may not yet have enough seasons of samples to be classified.
How this site uses the data
Pages use the EEA dataset "Bathing Water Directive – Status of bathing water, 2025 v1.0". Only sites with a 2025 entry are included. Classification history starts with the first season of the current scheme in each country: 2011 for Greece and 2012 for Croatia. Earlier seasons used a different scheme and are not shown.
Greek site names are published in capital letters in the dataset; this site shows them in title case. Regions are assigned from each site's coordinates using Natural Earth administrative boundaries; a site that is not clearly inside one region is not matched.
A site gets its own page only if it has a current class, a region and at least four classified seasons since the scheme change. All sites, including those without a page, are counted in the regional and national statistics.
All text on the site is generated from the data with fixed templates. Nothing is written by hand about individual sites.
