Ellensbrook Wind Stats

The figure describes how often and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Ellensbrook, located 45 km away (28 miles). There are too few 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 Ellensbrook 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 Ellensbrook. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of 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 10% of the time (3 days each May) and blows offshore 36% of the time (10 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 3 days at Ellensbrook
