Asu Wind Statistics, Novembro averages since 2006
The graph shows how often and how strongly the wind blows from different directions through a typical November. The biggest 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 2387 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. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Asu blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Asu. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 48% of the time (14 days each November) and blows offshore 57% of the time (17 days in an average November). During a typical November 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.
