Praia do Medão Grande faces W, open to the prevailing swell and wind. For canoeing that is the hard direction: expect the surface to be workable only when the forecast genuinely drops, not on an average day.
Today's wind is offshore at 11 kn. Blowing off the land keeps the surface flatter near the beach for canoeing, but it also pushes you out — stay inside where you can comfortably get back.

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, exposed Atlantic sandy beach backed by a large dune system and flanked by sandstone cliffs, with no reef or rock hazards in the water. The sandy beach break produces powerful, hollow, fast waves up to 4 m on big swells, working best on south and west swells with north/east wind, and has hosted championship surf events. Tidal range is roughly 0.7-3.3 m; low-to-mid tide forms the wave best. Lifeguarded 1 June-15 Sept 2026.
