Airport Lefts Wind Statistics, Abril averages since 2006
The graph shows how often and how strongly the wind blows from different directions through a typical April. 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 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Airport Lefts, located 33 km away (21 miles). There are insufficient 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 prevailing wind at Airport Lefts 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 Airport Lefts. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 29% of the time (9 days each April) and blows offshore 85% of the time (26 days in an average April). During a typical April winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Airport Lefts
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.
