Cala Reona faces S, and that aspect decides whether the day's wind arrives clean off the water or broken up by the land — which matters more for windsurfing than the forecast speed alone.

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, largely unspoilt south-facing cove flanked by black cliffs at the edge of a protected regional park. The bottom is fine sand with some pebbles and gravel; clear, calm water suits swimming and diving rather than surf or wind sports. Vehicle access to the park is heavily restricted in peak summer (shuttle bus only), and overnight stays are banned. A lifeguard operates in July and August, with a first-aid point staffed mid-June to mid-September.
