Blue Duck Stream Wind Stats

The figure describes how commonly and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies 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 Blue Duck Stream, located 30 km away (19 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Blue Duck Stream blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Blue Duck Stream. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 14% of the time (4 days each May) and blows offshore 28% of the time (9 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Blue Duck Stream
