Built from the sea floor up.

Seafloor mapping
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.
National met-office wind models
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.
Coastal propagation
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.
Per-sport scoring
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.
In context.
A small, isolated cove reached only on foot via a coastal path, with fine sand throughout, facing NNW into a sheltered bay. No facilities, no lifeguard cover. Rocks and rock pools are exposed at low tide on this rocky stretch, with a large tidal range (up to 8-9 m on springs); beach choice depends on wind and tide. Suited to quiet swimming, rock-pooling, and opportunistic wind/kite launching. Dogs banned 1 May-30 September.
