Forecasts come from ~8 km resolution models: very local effects (a sheltering pier, a lagoon pass) are not captured.
Sea-state data comes from a marine model cell about 11.9 km from this point — local nearshore conditions can differ.
Wave heights are significant heights: individual waves up to 2× this height still occur.
Four wave models are compared for this point: EWAM, GWAM, Météo-France WAM and ECMWF WAM.
Tide times derived from modelled sea level (± a few tens of minutes) — not official tide tables.
Missing data is shown as missing — never silently estimated.

Good visibility.
Loss of bearings and collision risk
Post-rain pollution · 0 mm over 24 h
When it rains hard, runoff from roads and fields and sewer overflows carry bacteria out to sea. Nothing significant has fallen in the last 24 hours.
Official sampling is weekly at best; between two samples, recent rain is the recognized warning signal (EEA)
Jellyfish: no recent info. If you're there, tell us what you see — even “none” helps the next swimmer.
Water quality · Excellent · 2025 season
Computed from the samples of the last four bathing seasons. It says what the water here has been, not what it is today: after heavy rain, even an excellent beach degrades for a day or two.
Health authority classification (EU directive 2006/7/EC), published once per bathing season
In all cases: bright swim cap and tow float so boats can see you.
