Praia da Mareta faces SE, away from the prevailing Atlantic swell. For surfing that means it needs a specific direction to work rather than picking up the everyday groundswell, so it is a spot to check rather than assume.
Today's wind is offshore at 9 kn. That is the direction you want for surfing — it holds the face up and clean instead of crumbling 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 sheltered, SSE-facing town beach roughly 750-800 m long, protected by a promontory to the west and a headland to the east. Sandy beach break with shifting sandbanks gives left- and right-handers, though rideable waves are very inconsistent; submerged rocks lie near the cliffs at both flanks, and weever fish are a hazard in the sand. Blue Flag certified with summer lifeguards. Mid tide suits surfing best; low tide gives the most forgiving central entry.
