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
Verified break location with regional surf context. Spot-specific geometry is still awaiting calibration.
Timing
NE–E offshore · often early
Break and tidal range 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.
