There are insufficient 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 dominant wind at Porth Ceriad blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Porth Ceriad. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.
