Plage de la Grève Blanche faces NE, away from the prevailing Atlantic swell. For surfing that means it needs a specific direction to work rather than picking up the everyday groundswell, so it is a spot to check rather than assume.
Today's wind is cross-shore at 7 kn. Straight cross-shore sits between the two for surfing — the face stays rideable but the wall is less organised than on a clean offshore.
Over the published window Plage de la Grève Blanche clears 60/100 for surfing at Beginner, Intermediate levels — that is who this spot is for on this sport. Today, 0 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 small, sheltered sandy cove with some pebbles and rock, tucked behind a harbour and facing NE into a bay across from a tidal island. The protected orientation produces calm water rather than surf, suiting family swimming, paddling and flat-water kite, wing or windsurf sessions. Dogs are banned 1 May-30 September; the beach is smoke-free. No lifeguard cover. The bay's tidal range reaches 8-9 m on springs, drying much of the beach at low tide.
