Praia do Porto do Seixal faces NE, 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 onshore at 4 kn. Onshore is the awkward one for surfing: it adds chop and pushes the wave over before it can stand up.

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 black volcanic-sand beach on Madeira's north coast, sheltered by steep green cliffs with a waterfall visible from the water. Unusually for the island, the bottom is soft sand rather than rock, producing reliable left and right surf peaks — gentler on smaller summer swells, more powerful in autumn-winter, with rocks at the edges. Surfing, paddling, and snorkelling are practised here. Mid-to-high tide suits entry and exit; lifeguard cover is unconfirmed.
