Is the water clean at Port Lenn?
Port Lenn is a coastal bathing site with an official EU Bathing Water rating of Sufficient for the 2025 season — meets the minimum EU 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, Toilets, and Beach bar. You can park about ~90 m away.
Over the 11 classified seasons on record, 10 have come back Excellent or Good — a track record worth checking each year rather than assuming. 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. Worth noting: the rating slipped from Good to Sufficient in 2025, so it's especially worth checking the latest local advisories. Port Navalo — the closest town — sits about ~600 m from here.
Worth remembering: “Sufficient” 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 Morbihan. There are 7 places to eat within a kilometre — Le Petit Port'Na is the closest, about ~50 m away.
Frequently asked questions
Is the water at Port Lenn safe right now?
Technically yes, though it's worth being careful: Port Lenn's 2025 rating is Sufficient, the bottom of the passing range, so look for local advisories before swimming.
How cold or warm is the water at Port Lenn today?
As of the latest update, the sea temperature at Port Lenn is around 21°C — see the “Right now” panel above for live conditions. That's the reading right off Morbihan.
What's the best month to visit Port Lenn for swimming?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch. That applies to the water around Morbihan.
What's behind the water quality rating shown above?
National authorities sample the water for intestinal enterococci and E. coli bacteria through the bathing season and report the full-season results to the European Environment Agency each spring for the season just finished, which assigns one of four annual classifications — Excellent, Good, Sufficient or Poor — under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
How do I get to Port Lenn without a car?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Tavéno, about ~60 m away. The nearest town is Port Navalo, about ~600 m away.
