Praia do Martinhal faces SE, so the prevailing westerly comes over the land before it reaches you. For wing foiling that usually means a gustier, less predictable flow than the raw wind speed suggests.
Today's wind is offshore at 9 kn. Offshore is the one to be careful with for wing foiling — a failure blows you away from the beach, so it is a spot for a safety boat or a change of plan rather than a solo session.
Over the published window Praia do Martinhal clears 60/100 for wing foiling at Intermediate, Advanced, Expert levels — that is who this spot is for on this sport. Today, 9 of 11 daylight hours clear that line at Intermediate.

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, SE-facing sandy bay about 650 m long, shielded from the dominant Atlantic swell by a headland. In summer the Nortada trade wind flattens the water, making this a flat-water windsurfing and kitesurfing venue. The sandy bottom slopes gently, with a rocky area at the eastern end and limestone islets just offshore. Blue Flag certified with summer lifeguards. Winter south winds bring chaotic shorebreak and strong currents.
