Tides and currents use the Météo-France global ocean model via Open-Meteo at roughly 8 km resolution. Sea level includes tide and atmospheric effects and is referenced to global mean sea level, not a local chart datum. Coastal accuracy is limited; never use this for navigation.

The break

Beach break

Community-mapped location with regional surf context. Spot-specific geometry is still awaiting calibration.

Timing

SW–W offshore

Section dependent. Re-check local observations and the lineup before you paddle out.

Data note

Fallback preview

Wave guidance, tide phase and offshore currents are modelled unless a nearby buoy observation is shown.
