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 near-circular, horseshoe-shaped bay on Menorca's north coast, its narrow mouth blocking swell to keep the water calm and shallow. Fine pale sand runs about 650m, with small Posidonia meadows in parts of the bay and rocky areas at its extremes suited to snorkeling. This is flatwater, not a surf or wind/kite spot. Swimmers must stay within a buoy-marked bathing zone due to heavy boat traffic; lifeguards patrol seasonally (15 May-15 October).
