Aisling's Beach Wind Statistics, May averages since 2006
The graph illustrates how often 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 indicates the strength, with dark blue strongest. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aisling's Beach, located 7 km away (4 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Aisling's Beach blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aisling's Beach. 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 May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 25% of the time (8 days each May) and blows offshore 62% of the time (18 days in an average May). Over an average May winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Aisling's Beach
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.
