Plage du Port Blanc faces W, 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-offshore at 8 kn. Leaning offshore, so the face should still stand up clean for surfing — not the glassy hold of a straight offshore, but the right side of neutral.
Over the published window Plage du Port Blanc 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, 2 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage du Port Blanc ranks 21st 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 small, wild, largely undeveloped west-facing cove with a shelving, rocky entry, tide-dependent between a pebbly high-tide shore and sandy low-tide areas. Suited to calm-water swimming and family use rather than surf. A marked bathing zone and separate kite/watersports zone apply in season, with a 5-knot limit within 300 m of shore. Unsupervised, though the nearby SNSM Primel-Plougasnou station offers a 24-hour, 15-minute-response rescue service.
