Willyabrup Wind Stats

The rose diagram illustrates how commonly and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Willyabrup, located 32 km away (20 miles). There are too few 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 Willyabrup blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Willyabrup. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (3 days each May) and blows offshore 40% of the time (11 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 2 days at Willyabrup
