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 Double Mouth blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Double Mouth.
