Is the water clean at Plage Pollux?
Thinking of swimming at Plage Pollux? The short answer: its official EU Bathing Water rating for 2025 is Poor — below the EU standard; swimming may be discouraged or restricted by local authorities. That rating is set once a year under the EU Bathing Water Directive, from a full season of testing for intestinal enterococci and E. coli reported to the European Environment Agency the following spring, so the 2025 season's grade appeared in spring 2026 and the 2026 season won't be graded 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's been a consistently reliable spot too — the rating has held at Poor for 9 straight years. There's parking about ~270 m from the beach.
Over the 11 classified seasons on record, 0 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, June–October is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. The nearest town, Kourou, is about ~900 m away.
“Poor” 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 are 29 places to eat within a kilometre — Le Samscilla is the closest, about ~310 m away.

Who measures the water quality rating, and how?
It's based on official water samples: authorities test for intestinal enterococci and E. coli through the season, then report the full-season results to the European Environment Agency each spring, which assigns one of four grades — Excellent, Good, Sufficient or Poor. A few national authorities, including Croatia's IZOR, also publish individual samples during the season itself, ahead of that annual report — that isn't yet available for Plage Pollux.

By car, it's easy — parking is right by the beach. There's a bus stop about ~610 m from the beach. There's a ferry landing about ~1.9 km from the beach. The nearest town is Kourou, about ~900 m away.
