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 quiet, unsupervised Atlantic beach at a river mouth, backed by a large dune and forest, with vast sandy shoreline and some pebbles. Not generally considered good for surfing; the river offers calmer, sheltered water suited to families, though shifting sandbars and current add hazard. Dogs and nudism are not permitted. No lifeguards are stationed here. Tides are significant, roughly 0.7–3.3 m, with river current interacting with tidal flow at entry.
