Plage de Siouville faces W, 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 cross-offshore at 7 kn. Leaning offshore, so a failure drifts you away from the beach rather than back to it — rideable for kite surfing, but not the direction to push your luck in.
Over the published window Plage de Siouville 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, 9 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage de Siouville ranks 20th for kite 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 fine-sand bay facing west-northwest between dunes and rocky headlands, Blue Flag-rated since 1988, popular for surfing, kitesurfing and windsurfing. Waves suit learners but turn hollow in winter swell, working best on northwest-to-west swell with east winds. Powerful tidal currents from the nearby Raz Blanchard affect the area, and a submerged metal cage sits in the wave zone at low tide.
