Asu Wind Statistieken, January gemiddelde vanaf 2006
The figure illustrates how frequently and how strongly the wind blows from different directions through a typical January. The largest 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 the darkest shade of blue. It is based on 2372 NWW3 forecasts of wind since since 2007, 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. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing 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. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 58% of the time (18 days each January) and blows offshore 69% of the time (21 days in an average January). During a typical January 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.
