Boobs Wind Statistics, Spring averages since 2006
This image illustrates how often and how strongly the wind blows from different directions through a typical southern hemisphere spring. The longest 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 deep blue. It is based on 6516 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Boobs, located 24 km away (15 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 most common wind at Boobs blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Boobs. By contrast, dominant spokes illustrate 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 9% of the time (8 days each southern hemisphere spring) and blows offshore 38% of the time (15 days in an average southern hemisphere spring). In a typical southern hemisphere spring winds stronger than >40kph (25mph) are expected on 7 days at Boobs
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.
