There are too few 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 most common wind at Dee Why Point blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Dee Why Point.
