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 10.9 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.

Water clarity generated using E.U. Copernicus Marine Service Information.
Windows, comfort score and verdicts are computed by oswim from this data — modified values, not the institutes' raw figures.
min 12 · max 31 km/h · west sector · gusts 55 km/h
Rip / shore-break spot · 2.6 – 3.2 m
Waves are high enough to power this spot's rips or shore break. Stay in shallow water and away from channels.
Curated spot hazard · trigger ½ of the NWS 1.2 m rip step (engineering choice)
Thunderstorm · None forecast
No thunderstorms forecast.
World Triathlon: stop on lightning
Offshore wind · 11 – 31 km/h
No wind-driven offshore drift.
RNLI / lifeguard warning · measured drift (coastguard): 2–4 % of the wind · Beaufort scale
Visibility · 4 – 43 km
Good visibility.
Loss of bearings and collision risk
Post-rain pollution · 0 – 0.5 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.
In all cases: bright swim cap and tow float so boats can see you.
Consolidated ladder: World Aquatics / World Triathlon / FFTri rules + manufacturer thermal guides
Depth as you head out: 200 m → 2.3 m · 400 m → 6.4 m · 800 m → 8.9 m
Modelled depths (EMODnet, the European seabed model), stated without the tide: at low water there is less. A swimming bearing, never a navigation aid.
Nearest lifeguarded beach: (2.0 km).
Rip currents
Powerful currents can form and pull you out to sea — sometimes faster than an Olympic swimmer. If caught: don't fight it, swim parallel to the beach, then angle back in.
Shore break
Waves break directly onto the sand: spine and neck injuries occur from 1 m up. Never dive head first; go through waves sideways.
Coastal path and small car parks. Unsupervised; swimming banned by local order on most coves.
Worth knowing
This shoreline shelters marine life typical of wave-battered rocks, from limpets to marbled crabs darting between the crevices.
