The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue.

There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Mahanga Point blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Mahanga Point.
