Airport Rights Wind Statistics, Winter averages since 2006
This chart illustrates how commonly and how strongly the wind blows from different directions over a normal southern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Airport Rights, located 33 km away (21 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 Airport Rights 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 Rights. By contrast, 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 southern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (3 days each southern hemisphere winter) and blows offshore just 98% of the time (89 days in an average southern hemisphere winter). Over an average southern hemisphere winter winds exceeding >40kph (25mph) are not expected, but 20 have winds on the range 30-40 (19-25) at Airport Rights
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.
