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 1.3–2.5 km — UK Met Office UKV, Météo-France AROME HD and AROME, 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 cliff-backed bay in a protected natural park, with a roughly 500 m sandy beach break offering peaks along its length, forgiving when small, plus a rocky point break at the northern edge with a boulder-strewn line-up carrying rock-cut hazard, worst at lower tides. Submerged rocks also sit mid-beach, notable at high tide. Lifeguards are present in summer, typically June to September; beach-level parking is limited to drop-off and residents.
