Is the water clean at Porsmilin?
Porsmilin sits on a stretch of coast classed as a coastal bathing site, carrying an official EU Bathing Water rating of Good for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow 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 sits in Finistère. You can park about ~60 m away.
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. Plouzané — the closest town — sits about ~5.2 km from here.
That “Good” 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. It's been a consistently reliable spot too — the rating has held at Good for 2 straight years. There are 4 places to eat within a kilometre — Mille Sabords is the closest, about ~340 m away.
Frequently asked questions

What's the best month to visit Porsmilin for swimming?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Finistère.
What does the water quality rating actually measure?
The grade comes from a full season of official sampling for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive, which assigns Excellent, Good, Sufficient or Poor. Some countries (Croatia, via IZOR) also publish individual in-season samples ahead of that report; Porsmilin doesn't have that feed yet.

By car, it's easy — parking is right by the beach. By bus, the nearest stop is Portez, about ~340 m away. The nearest town is Plouzané, about ~5.2 km away.
