Grande Plage faces S, and that aspect decides whether the day's wind arrives clean off the water or broken up by the land — which matters more for wing foiling than the forecast speed alone.
Today's wind is cross-shore at 20 kn. Straight cross-shore is the classic wing foiling direction: it lets you hold a line along the beach rather than fighting to get back to it.
Over the published window Grande Plage clears 60/100 for wing foiling at every ability from Beginner to Expert — an unusually broad spot, which normally means a range of conditions rather than one narrow sweet spot. Today, 6 of 11 daylight hours clear that line at Intermediate.

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 south-facing sandy urban beach around 400-500 m long, with a fine, gently shelving bottom and no reef, set against an industrial backdrop with tankers anchored offshore.
