Plage de Port-Lenn faces W, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow windsurfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is offshore at 5 kn. Offshore is the one to be careful with for windsurfing — a failure blows you away from the beach, so it is a spot for a safety boat or a change of plan rather than a solo session.
Over the published window Plage de Port-Lenn clears 60/100 for windsurfing 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, 2 of 10 daylight hours clear that line at Intermediate.
Among the 29 scored spots within reach today, Plage de Port-Lenn ranks 24th for windsurfing. 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 small, partially sheltered beach of mixed sand and pebble at the entrance to the Gulf of Morbihan, overlooking a fishing harbour with moored boats. The western side is sandy, the eastern side mostly pebbly and more exposed at low tide; numerous mooring buoys offshore are a hazard for swimmers. It's a calm-water setting rather than a surf spot. Dogs are banned April 15–September 15 and shellfish gathering is prohibited year-round.
