Apollo Bay Wind Statistics, May averages since 2006
This image illustrates how often and how strongly the wind blows from different directions through a typical May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Apollo Bay, located 31 km away (19 miles). There are too few 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 dominant wind at Apollo Bay blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Apollo Bay. 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 May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each May) and blows offshore 57% of the time (18 days in an average May). During a typical May winds stronger than >40kph (25mph) are expected on 5 days at Apollo Bay
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.
