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 dark blue.

There are insufficient 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 Port Isabel blows from the E. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Port Isabel.
