Anna Bay-Morna Point Wind Statistics, September averages since 2006
The figure illustrates how frequently and how strongly the wind blows from different directions through a typical September. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 2400 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anna Bay-Morna Point, located 25 km away (16 miles). There are not enough 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 most common wind at Anna Bay-Morna Point blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anna Bay-Morna Point. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (2 days each September) and blows offshore 30% of the time (4 days in an average September). During a typical September wind stronger than >40kph (25mph) was predicted for only a single days at Anna Bay-Morna Point
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.
