Is the water clean at Kervilen?
Thinking of swimming at Kervilen? The short answer: its official EU Bathing Water rating for 2025 is Excellent — the highest official classification under the EU bathing-water assessment. That rating is set once a year under the EU Bathing Water Directive, from a full season of testing for intestinal enterococci and E. coli reported to the European Environment Agency the following spring, so the 2025 season's grade appeared in spring 2026 and the 2026 season won't be graded until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. It's been a consistently reliable spot too — the rating has held at Excellent for 2 straight years. There's parking about ~60 m from the beach.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. The nearest town, La Trinité-sur-Mer, is about ~1.4 km away.
“Excellent” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above.

Who measures the water quality rating, and how?
Once a year, national authorities report a full season of testing for intestinal enterococci and E. coli to the European Environment Agency, which grades the season Excellent, Good, Sufficient or Poor under the EU Bathing Water Directive. A handful of countries, including Croatia via IZOR, also publish individual in-season samples ahead of that report — Kervilen doesn't have that feed set up yet.
