Is the water clean at Glenan-St Nicolas?
Glenan-St Nicolas is a coastal bathing site with an official EU Bathing Water rating of Excellent for the 2025 season — the highest official classification under the EU bathing-water 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 Toilets and Benches.
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. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years.
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 Finistère. There are 2 places to eat within a kilometre — La Boucane is the closest, about ~410 m away.
Frequently asked questions
Can you safely swim at Glenan-St Nicolas?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 11 of the 11 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 11 straight years.
How warm is the sea at Glenan-St Nicolas right now?
That reading, around 23°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Finistère.
Which month has the warmest sea at Glenan-St Nicolas?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Finistère.
What's behind the water quality rating shown above?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Glenan-St Nicolas isn't yet covered by that in-season feed.
How do I get to Glenan-St Nicolas without a car?
There's no parking mapped within 1.5 km of Glenan-St Nicolas, so plan on a walk, or arrive early once it gets busy. There's a ferry landing about ~530 m from the beach.
