Grange Chine faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow windsurfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is offshore at 9 kn. Offshore is the one to be careful with for windsurfing — a failure blows you away from the beach, so it is a spot for a safety boat or a change of plan rather than a solo session.

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 quiet, undeveloped shingle-and-sand beach on the Isle of Wight's exposed south-west coast, reached via a chine and path, within a National Landscape and SSSI. The seabed of mud, sand, shells and submerged rocks has a history of shipwrecks; the SW-facing beach break supports surfing, windsurfing and diving, with no reef or point break. No lifeguard patrol, no watersports zoning. Dogs permitted year-round; landslip instability affects the chine slopes.
