The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by deep blue. It is based on 3430 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to The Bombie and Boat Ramp, located 45 km away (28 miles). There are too few 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 prevailing wind at The Bombie and Boat Ramp blows from the SW.
