Armadale Bay Wind Statistieken, March gemiddelde vanaf 2006
The graph illustrates how frequently and how strongly the wind blows from different directions over a normal March. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Armadale Bay, located 50 km away (31 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 dominant wind at Armadale Bay blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Armadale Bay. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each March) and blows offshore just 41% of the time (13 days in an average March). Over an average March winds stronger than >40kph (25mph) are expected on 11 days at Armadale Bay
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.
