What kind of beach is this?
This beach belongs to a small coastal village. It's usually calmer than a resort or town beach, though a popular village spot can still fill up on the best summer days.

Is the water clean at Kerdeniel?
Kerdeniel is a coastal bathing site with an official EU Bathing Water rating of Good for the 2025 season — meets the EU bathing-water 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 and Benches. You can park about ~270 m away.
Over the 11 classified seasons on record, 7 have come back Excellent or Good — a track record worth checking each year rather than assuming. 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. Portsall — the closest town — sits about ~500 m 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 — Le Kraken is the closest, about ~370 m away.

What's the ideal time of year to swim at Kerdeniel?
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 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; Kerdeniel doesn't have that feed yet.
