Praia Grande faces SW, open to the prevailing westerlies, so the wind arrives off the water rather than filtered through the land — the clean, steady flow kite foiling wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is cross-onshore at 5 kn. Leaning onshore, which is the forgiving side for kite foiling: you can hold a line along the beach and anything that goes wrong still drifts you in.
Over the published window Praia Grande 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, 7 of 11 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Praia Grande ranks 6th 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 wide, 627m golden-sand crescent at an estuary mouth, sheltered almost entirely from Atlantic swell by a port breakwater, giving calm water for flat-water paddling, swimming and light-wind sailing rather than surf. Boulders divide the main beach from a smaller section near a fort; low tide allows a walk around the fort, cut off as the tide rises. Windsurfing, kayaking and paddleboarding are permitted. Lifeguards cover June-September; Blue Flag certified.
