Is the water clean at Cale de Mordreuc?
Thinking of swimming at Cale de Mordreuc? 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 4 straight years. You can park about ~30 m away.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. Pleudihen-sur-Rance — the closest town — sits about ~1.8 km from here.
Worth remembering: “Excellent” isn't a live reading, it's an annual grade — Excellent, Good, Sufficient or Poor — set once a year from that season's water samples and describing the average, not this afternoon's conditions. For what the sea is doing right now, check the “Right now” panel and 7-day outlook above. It sits in Côtes-d'Armor. There are 2 places to eat within a kilometre — La cale de Mordreuc is the closest, about ~40 m away.

What does the water quality rating actually measure?
National authorities sample the water for intestinal enterococci and E. coli bacteria through the bathing season and report the full-season results to the European Environment Agency each spring for the season just finished, which assigns one of four annual classifications — Excellent, Good, Sufficient or Poor — under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
