Asu Wind Statistics, June averages since 2006
This chart illustrates how commonly 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 dark blue. It is based on 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Asu, 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 most common wind at Asu blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Asu. Converseley, 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 June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 58% of the time (17 days each June) and blows offshore 67% of the time (20 days in an average June). During a typical June winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Asu
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
