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 small, semi-wild Atlantic cove facing NNW into open ocean, with fine sand backed by low cliffs and a rocky outcrop on the northern side that shelters part of the bay. Exposed to Atlantic swell, it is used for surfing and bodyboarding, with windsurfing and kitesurfing also practised here. It is described as seasonally lifeguarded, though exact hours are unpublished. Tidal range is large; rocky outcrops become submerged diving platforms at high tide.
