The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3430 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to The Rock-Costa Azul, located 21 km away (13 miles). There are not enough recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common wind at The Rock-Costa Azul blows from the SSW.
