Plage de Trez Cao 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 windsurfing than the forecast speed alone.
Today's wind is cross-shore at 5 kn. Straight cross-shore is the classic windsurfing direction: it lets you hold a line along the beach rather than fighting to get back to it.

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 small, south-facing sandy beach in Trégunc, Finistère, sheltered from the prevailing westerly and north-westerly winds and rated for excellent water quality. Typically calm and family-friendly, it can produce a sand beach break when wind blows from the south. No rock or reef hazards are documented. It is not among the commune's officially supervised beaches, so bathing is unsupervised; the shore remains accessible even at low tide.
