The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Iluka-North Wall, located 16 km away (10 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Iluka-North Wall blows from the E.
