Plage de la Grève Blanche faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow wing foiling wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is onshore at 8 kn. Onshore is the safest direction for wing foiling here — anything that goes wrong drifts you back to the beach — at the cost of a choppier surface.

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 1 km fine white-sand Atlantic beach on Finistere's south coast, facing SW toward a nearby lighthouse. Unsupervised and multi-use, it hosts windsurfing, catamaran, kayak, surfing and kitesurfing via a seasonal nautical centre (July-August) that hires gear but gives no rescue cover. Algae-covered rocks emerge at low tide, so mid-to-high tide suits entry and exit best. No lifeguard at any time; dogs on lead, seasonal limits apply.
