Plage de Mousterlin faces SW, open to the prevailing swell and wind. For swimming that is the hard direction: expect the surface to be workable only when the forecast genuinely drops, not on an average day.
Today's wind is cross-offshore at 5 kn. Light enough that the surface should stay workable for swimming.
Over the published window Plage de Mousterlin clears 60/100 for swimming 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, 9 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage de Mousterlin is level with one other at the top for swimming — nothing nearby is scoring better, so pick on distance.
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 wild, exposed 5 km fine-sand Atlantic beach facing SW, the area's hub for kitesurfing and land yachting, with wide sand flats at low tide for launching and a beach break offering surf and bodyboarding on westerly swell. No rock or reef hazards are reported. Lifeguards patrol a flagged zone 13:30-19:30 in summer. Dogs are banned June-September. The western end can vanish at high tide, and currents are stronger than at sheltered beaches nearby.
