Plage Saint-Jacques faces S, and that aspect decides whether the day's wind arrives clean off the water or broken up by the land — which matters more for kite foiling than the forecast speed alone.
Today's wind is cross-shore at 6 kn. Straight cross-shore is the classic kite foiling direction: it lets you hold a line along the beach rather than fighting to get back to it.
Over the published window Plage Saint-Jacques clears 60/100 for kite foiling 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, 10 of 10 daylight hours clear that line at Intermediate.
Among the 28 scored spots within reach today, Plage Saint-Jacques ranks 4th for kite foiling. 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 sheltered, SSW-facing family beach on the Rhuys peninsula with fine white sand and a gently shelving, calm-water entry — no surf break. A Centre Nautique here runs sailing, kayak, catamaran, windsurf and paddle sessions, making it a flat-water hub. Rocky schist outcrops on the western flank are submerged at high tide but exposed at low tide, making entry difficult there; the central sandy section is easiest.
