Plage de Tresmeur faces SW, open to the prevailing swell and wind. For e-foiling 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-shore at 7 kn. Light enough that the surface should stay workable for e-foiling.
Over the published window Plage de Tresmeur clears 60/100 for e-foiling at Advanced, Expert 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 large sandy tourist beach beside a marina, with a flat-water freeride character rather than a surf break — the bay dampens swell, while SW wind makes it a rare windsurf, kitesurf and wingfoil spot here. Watersports work only at low tide, since the harbour breakwater sits too close at high water; moored boats are a hazard then. An SNSM rescue post operates at the entrance in July and August. Dogs banned by day May-September.
