Plage de Port Blanc faces SW, open to the prevailing swell and wind. For kayaking 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 kayaking.
Over the published window Plage de Port Blanc clears 60/100 for kayaking 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 Port Blanc ranks 21st for kayaking. 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 compact, roughly 200 m SW-facing sandy family beach flanked by two rocky promontories at the mouth of the Gulf of Morbihan. The cove itself is calm and sheltered for bathing, but it sits beside a powerful tidal channel with currents reaching up to 8 knots at springs; swimming near the headlands is explicitly prohibited. Kitesurfing is not permitted here (it is zoned to a beach further along).
