Sandy Bay Wind Stats

This image illustrates how often and how strongly the wind blows from different directions over a normal April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Sandy Bay, located 5 km away (3 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Sandy Bay blows from the ENE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Sandy Bay. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 10% of the time (3 days each April) and blows offshore 41% of the time (11 days in an average April). Over an average April wind stronger than >40kph (25mph) was forecast for only a single days at Sandy Bay
