Châtelaillon-Plage faces W, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow kite foiling wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is onshore at 10 kn. Onshore is the safest direction for kite foiling here — anything that goes wrong drifts you back to the beach — at the cost of a choppier surface.
Over the published window Châtelaillon-Plage clears 60/100 for kite 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, 10 of 10 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 wide Atlantic bay beach facing west, with a sandy bottom giving way to mudflats and oyster beds with sharp shells at low tide. Sheltered and flatwater, it suits kitesurfing, windsurfing, and calm swimming rather than surfing. Kitesurfing is banned 15 June-15 September; outside that window kiters launch from the left side, clear of oyster-farming areas. Lifeguards supervise in summer. High tide is preferred, as low tide means a long mudflat carry.
