Alexandra Headland Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical June. The longest 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 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Alexandra Headland, located 43 km away (27 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 most common wind at Alexandra Headland blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Alexandra Headland. 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. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (2 days each June) and blows offshore 42% of the time (13 days in an average June). In a typical June winds stronger than >40kph (25mph) are expected on 3 days at Alexandra Headland
