Plage de Port Blanc faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow kite surfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is offshore at 10 kn. Offshore is the one to be careful with for kite surfing — 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 Blanc clears 60/100 for kite 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, 8 of 10 daylight hours clear that line at Intermediate.
Among the 28 scored spots within reach today, Plage de Port Blanc is level with one other at the top for kite surfing — 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.
An unsupervised, exposed Atlantic beach break on the peninsula's wild coast, reached via cliff access. Fast, powerful right-handers break over sand with rocks, from around 0.5 m to 3 m of swell — best with southwest swell and northeast offshore wind; summer is typically flat, suiting experienced surfers only. Swimming is prohibited by ordinance, with no lifeguard cover. Best on a rising tide; closes out at high tide, with strong currents and rocks.
