Abras Wind Statistics, Spring averages since 2006
This chart describes how frequently and how strongly the wind blows from different directions through a typical southern hemisphere spring. 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 the darkest shade of blue. It is based on 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Abras, located 21 km away (13 miles). There are too few 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 Abras blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Abras. By contrast, dominant spokes show 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 southern hemisphere spring, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0% of the time (0 days each southern hemisphere spring) and blows offshore just 0% of the time (0 days in an average southern hemisphere spring). In a typical southern hemisphere spring winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Abras
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.
