Is the water clean at Saint Cieux?
Thinking of swimming at Saint Cieux? The short answer: its official EU Bathing Water rating for 2025 is Excellent — the highest official classification under the EU bathing-water 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. It's been a consistently reliable spot too — the rating has held at Excellent for 5 straight years. There's parking about ~110 m from the beach.
Looking to avoid the busiest weeks? The water is typically warmest around August, with the most reliable swimming window running July–September; outside that stretch you'll find a cooler sea but a quieter beach. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. On site you'll find Sandy shore, Showers, and Toilets. The nearest town, Lancieux, is about ~400 m away.
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 Côtes-d'Armor. There are 13 places to eat within a kilometre — La Cabane à voile is the closest, about ~40 m away.
Frequently asked questions
Should you swim at Saint Cieux?
Saint Cieux is rated Excellent for 2025 — the top EU Bathing Water classification — with 11 of 11 classified seasons rating Excellent or Good, so yes. It's also held steady at Excellent for 5 straight years.
What's the current water temperature at Saint Cieux?
Treat the ~23°C above as illustrative only — Saint Cieux's live marine feed was down when this page was generated, and the figure will be replaced with a real reading automatically once it's back. That's the reading right off Côtes-d'Armor. On the modeled climatology here, August usually runs warmest.
When does Saint Cieux have the warmest water?
For the warmest water, aim for July–September — that's when the modeled sea temperature is typically at its best. That applies to the water around Côtes-d'Armor. Within that window, August is typically the single warmest month.
Where does the water quality rating come from?
It's based on official water samples: authorities test for intestinal enterococci and E. coli through the season, then report the full-season results to the European Environment Agency each spring, which assigns one of four grades — Excellent, Good, Sufficient or Poor. A few national authorities, including Croatia's IZOR, also publish individual samples during the season itself, ahead of that annual report — that isn't yet available for Saint Cieux.
What's the easiest way to reach Saint Cieux?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Église, about ~440 m away. The nearest town is Lancieux, about ~400 m away.
