Is the water clean at Port Blanc?
Port Blanc sits on a stretch of coast classed as a coastal bathing site, carrying an official EU Bathing Water rating of Excellent for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow 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 sits in Côtes-d'Armor. You can park about ~70 m away.
Over the 11 classified seasons on record, 8 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. Port Navalo — the closest town — sits about ~10 m from here.
That “Excellent” 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. Water quality here has been improving: the rating moved from Sufficient to Excellent in 2025. There are 7 places to eat within a kilometre — Ty Prenn is the closest, about ~60 m away.
Frequently asked questions
Is Port Blanc a safe beach for swimming?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 8 of the 11 classified seasons on record have rated Excellent or Good. Its rating has also been trending the right way, moving from Sufficient to Excellent in 2025.
How warm is the sea at Port Blanc 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 Côtes-d'Armor.
What's the best month to visit Port Blanc for swimming?
July–September is typically the most reliable swimming window, with the sea usually warmest in the second half of summer. That applies to the water around Côtes-d'Armor.
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; Port Blanc doesn't have that feed yet.
How do I get to Port Blanc without a car?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Cinéma, about ~180 m away. By ferry, the nearest landing is Port Navalo, about ~460 m away. The nearest town is Port Navalo, about ~10 m away.
