Is the water clean at Pors Mabo?
Pors Mabo is a coastal bathing site with an official EU Bathing Water rating of Sufficient for the 2025 season — meets the minimum EU standard in the latest annual assessment. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated 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. On site you'll find Sandy shore, Showers, and Toilets. There's parking about ~170 m from the beach.
Over the 11 classified seasons on record, 7 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. It's been a consistently reliable spot too — the rating has held at Sufficient for 4 straight years. The nearest town, Trébeurden, is about ~1.1 km away.
That “Sufficient” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. There's 1 place to eat near the beach — Le Molène, about ~1.0 km away.

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 — Pors Mabo doesn't have that feed set up yet.
