Backdoors Wind Stats

This image illustrates how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Backdoors, located 45 km away (28 miles). There are insufficient 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 prevailing wind at Backdoors blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Backdoors. 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 8% of the time (2 days each April) and blows offshore 29% of the time (9 days in an average April). Over an average April wind stronger than >40kph (25mph) was expected for only a single days at Backdoors
