Is the water clean at Port Riou?
Port Riou 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 ~300 m away.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. 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. Dinard — the closest town — sits about ~900 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. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. There are 43 places to eat within a kilometre — Sadi2 is the closest, about ~760 m away.

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 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 Riou doesn't have that feed yet.
