Satellite-derived bathymetry with 10 m pixels and 10 cm vertical resolution out to ~40 m depth. The shape of the seabed is what determines where and how waves break.
Most apps run a single global model at 9–25 km. We blend regional NWP from national meteorological offices at 1.3–2 km — UK Met Office UKV, Météo-France AROME HD, ItaliaMeteo ICON-2I — with ECMWF IFS for the 8-day horizon. Finer resolution means the sea breeze, cliff funnelling and bay shadowing that changes everything for a session.
A nearshore wave model propagates the spectrum across the bathymetric mesh — modelling refraction, shoaling, dissipation, focusing and breaking as it goes. Most apps stop at swell + wind. We go further.
10 sport models × 4 ability levels weight wave height, period, wind, tide and breaking conditions differently — calibrated against ridden sessions so the scores mean what they say.
A wide, 2.5 km sand beach backed by dunes and pine forest, calm and family-oriented most of the year, doubling as a sand-yachting and kite area in a dedicated summer zone. It is a sandy beach-break with left and right waves, but surf needs large, rare west swells. WWII concrete bunker remnants on the sand are a hazard, especially at low tide. Dogs banned 1 April-30 September; lifeguards cover 11:00-19:00, 2 July-31 August.
