Is the water clean at Lerat?
Lerat 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 Loire-Atlantique. There's parking about ~90 m from the beach.
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. The nearest town, Saint-Sébastien, is about ~1.3 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. There's 1 place to eat near the beach — friterie, about ~90 m away.

Who measures the water quality rating, and how?
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 Lerat doesn't have one published yet.

By car, it's easy — parking is right by the beach. By bus, the nearest stop is Sissac, about ~580 m away. The nearest town is Saint-Sébastien, about ~1.3 km away.
