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, sheltered south-southeast cove beneath limestone cliffs inside a natural park and marine reserve, with a sandy bottom giving way to rocky reef further out. Calm, clear water suits swimming, snorkelling, diving, kayaking and paddleboarding rather than surfing or wind sports; urchins on rocky sections make water shoes advisable. Fishing and spearfishing are banned. In summer the access road is restricted, with a shuttle bus and lifeguards present.
