Praia de Tanxil 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 surfing wants, and the reason gusts here are sea breezes rather than land turbulence.
Today's wind is cross-shore at 5 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.
Over the published window Praia de Tanxil 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, 0 of 11 daylight hours clear that line at Intermediate.
Among the 30 scored spots within reach today, Praia de Tanxil ranks 30th 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 small, sheltered sandy beach (220 m long, 50 m wide) inside a calm inner estuary in a town centre, with white coarse-to-medium sand and no rocks or reef. Consistently described as calm with only slight waves and not practicable for surfing, it suits swimming and relaxation. Dogs and nudism are not permitted, and there is no wheelchair access. Lifeguard cover is unclear: one source reports none, another lists seasonal rescue resources.
