Plage de Tanchet faces SW, straight into the prevailing Atlantic swell window — the reason it has waves at all, and the reason it is rarely flat.
Today's wind is cross-onshore at 9 kn. Leaning onshore, so expect some texture on the face for surfing — rideable, but short of clean.
Over the published window Plage de Tanchet clears 60/100 for surfing 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, 7 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage de Tanchet ranks 7th 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 west-southwest-facing beach at the southern tip of the bay, with a sandy beach break flanked by rocky reefs on both sides, forming the city's designated surf zone, used by surfers and bathers alike. A southward rip current is the main hazard, strongest near the reefs, most exposed at low tide. Kitesurfing requires a permit within an affiliated club. Lifeguards are on duty April-September; dogs are banned over that same period.
