Today plus the next two days are free for everyone — scored in 3-hour windows, just like the app. The full 8-day forecast lives in the 4Shor app.
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 roughly 300-metre arc of dark volcanic sand and pebbles beneath steep cliffside buildings, calm and clear, good for swimming, snorkelling, kayaking, and SUP; seabed slopes gradually, no surf break. Central and western sections are private beach clubs; a 5-metre waterline strip and the eastern section stay freely accessible. A pier carries ferry and hydrofoil traffic, so swimmers should avoid the boat lane. Lifeguard cover is expected in summer.
