Is the water clean at Guerzit?
Thinking of swimming at Guerzit? The short answer: its official EU Bathing Water rating for 2025 is Good — meets the EU bathing-water standard in the latest annual 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. Worth noting: the rating slipped from Excellent to Good in 2025, so it's especially worth checking the latest local advisories. There's parking about ~850 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 and Benches. The nearest town, Saint-Samson, is about ~1.1 km away.
Worth remembering: “Good” 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.

Should you swim at Guerzit?
Yes — Guerzit's 2025 rating is Good, one step below the top tier, with 11 of 11 classified seasons rated Excellent or Good. That said, the rating slipped from Excellent to Good in 2025, so it's worth checking for current local advisories too.

When should you plan a swimming trip to Guerzit?
For swimming, July–September is usually the best call — that's the modeled window when the sea here runs warmest. That applies to the water around Finistère. Within that window, August is typically the single warmest month.
How is bathing water quality actually assessed?
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 Guerzit.
