Statistiques de Vent de Aberdeen, moyennes sur Octobre depuis 2006
The figure illustrates how frequently and how strongly the wind blows from different directions over a normal October. The largest 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 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberdeen, located 20 km away (12 miles). There are too few 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 Aberdeen blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aberdeen. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (1 days each October) and blows offshore just 18% of the time (5 days in an average October). Over an average October winds stronger than >40kph (25mph) are expected on 2 days at Aberdeen
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.
