ADs/Doubles Wind Statistieken, May gemiddelde vanaf 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions over a normal May. The biggest 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 dark blue. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to ADs/Doubles, located 28 km away (17 miles). There are not enough 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 ADs/Doubles blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at ADs/Doubles. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, 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 May) and blows offshore just 3% of the time (1 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at ADs/Doubles
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.
