Is the water clean at Etang Lamotte?
Etang Lamotte sits on a stretch of coast classed as a lake 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 Ardennes. There's parking about ~100 m from the beach.
That rating has been consistent: every one of the 10 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. The nearest town, Brognon, is about ~1.5 km away.
“Excellent” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above.
Frequently asked questions
Is it safe to go in the water at Etang Lamotte?
Yes — Etang Lamotte carries the top EU Bathing Water classification, Excellent, for 2025, and 10 of its 10 classified seasons have rated Excellent or Good. It's also held steady at Excellent for 7 straight years.
What temperature is the sea at Etang Lamotte right now?
Treat the ~28°C above as illustrative only — Etang Lamotte'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 Ardennes. On the modeled climatology here, August usually runs warmest.
When should you plan a swimming trip to Etang Lamotte?
If you're planning around water temperature, July–September is the window to target — the modeled sea temperature is typically highest then. That applies to the water around Ardennes. Within that window, August is typically the single warmest month.
Where does the water quality rating come from?
Behind the annual grade: a season of testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive. A few countries, Croatia via IZOR included, also publish individual in-season samples ahead of that report, but Etang Lamotte doesn't have one published yet.
What's the easiest way to reach Etang Lamotte?
By car, it's easy — parking is right by the beach. The nearest town is Brognon, about ~1.5 km away.
