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.
This is a sheltered, gently shelving golden-sand beach on an ESE-facing shore, protected from prevailing south-westerly winds, giving calm, family-friendly water. It is a major hub for dinghy sailing, windsurfing, wing foiling, and paddleboarding, with sandy bottom throughout and no rock. Consistent surf is rare; surfers head to nearby exposed beaches instead. A no-craft bathing zone with a speed limit protects swimmers. It is not RNLI beach-lifeguarded.
