Praia da Sesmaria 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-shore at 7 kn. Straight cross-shore is the classic kite surfing direction: it lets you hold a line along the beach rather than fighting to get back to it.

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 remote, wide, sandy Atlantic beach break with left- and right-hand waves and a calmer bay section suited to beginners and children. Pinewoods back the shore, with a protected lagoon nature reserve about 500 m north where kitesurfing and windsurfing are banned to protect migratory birds. No lifeguard cover is documented for this beach itself. The shore is exposed with strong ocean waves; the beach widens considerably at low tide.
