Plage de la Tranche faces SE, 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 Tranche clears 60/100 for surfing at Beginner, Intermediate, Advanced levels — that is who this spot is for on this sport. Today, 8 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage de la Tranche ranks 11th for surfing. The order changes by discipline: the same conditions that put a spot top for one sport can drop it down the list for another.
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, sandy, southeast-facing Atlantic beach break shaped by jetty structures, producing left and right-handers rarely exceeding about 1 m due to sheltering; suitable for all levels but crowded in season, also used for kitesurfing and windsurfing, with a dedicated kite zone at a neighbouring beach. Low tide brings steeper waves, high tide softer ones. Dogs are banned on supervised beaches in summer daytime. Lifeguards cover late June-end August.
