Is the water clean at Garonne?
Garonne 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 Gironde. There's parking about ~570 m from the beach.
That rating has been consistent: every one of the 2 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, Arcachon, is about ~7.8 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.

When is the best time to swim at Garonne?
For the warmest water, aim for July–September — that's when the modeled sea temperature is typically at its best. That applies to the water around Gironde. Within that window, August is typically the single warmest month.
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 Garonne doesn't have one published yet.

By car, there's parking about ~570 m from the beach. By ferry, the nearest landing is Jetée du Canon, about ~2.1 km away. The nearest town is Arcachon, about ~7.8 km away.
