Is the water clean at Traon Erch?
Thinking of swimming at Traon Erch? The short answer: its official EU Bathing Water rating for 2025 is Sufficient — meets the minimum EU standard in the latest annual 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. Worth noting: the rating slipped from Good to Sufficient in 2025, so it's especially worth checking the latest local advisories. You can park about ~70 m away.
Over the 11 classified seasons on record, 8 have come back Excellent or Good — a track record worth checking each year rather than assuming. 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. Roscoff — the closest town — sits about ~1.6 km from here.
Worth remembering: “Sufficient” 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 Finistère. There are 2 places to eat within a kilometre — Ti'Nathy is the closest, about ~450 m away.
