There are not enough 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 Ter Heijde blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ter Heijde.
