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 14.3 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.

Depths from the global GEBCO grid (~450 m cells), stated without the tide: coarser than along European coasts, they say how it drops away offshore rather than what is under your feet. Never a navigation aid.
Stonefish
Highly venomous and invisible on coral or sandy bottoms. Never walk barefoot on the reef flat; thick booties are essential.
Boat traffic
A navigation channel or busy boating area is close by. Stay inside the marked swim zone, wear a bright cap and a tow float to be seen.
Pointe Vénus lighthouse car park. Busy at weekends, occasional supervision.
Worth knowing
It was here, at Point Venus, that Captain Cook observed the transit of Venus in 1769, giving the site its name.
