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 9.5 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.

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.
In all cases: bright swim cap and tow float so boats can see you.
