Back Bommie Wind Statistics, April averages since 2006

The rose diagram illustrates 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 indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 1920 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Back Bommie, located 9 km away (6 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 Back Bommie blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Back Bommie. 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. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each April) and blows offshore 32% of the time (10 days in an average April). In a typical April winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Back Bommie

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.
