Statistiques de Vent de Anna Bay-Morna Point, moyennes sur Automne depuis 2006
The graph illustrates how often and how strongly the wind blows from different directions through a typical southern hemisphere autumn. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 6580 NWW3 forecasts of wind since since 2007, 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. 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 Anna Bay-Morna Point blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Anna Bay-Morna Point. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 10% of the time (9 days each southern hemisphere autumn) and blows offshore 36% of the time (16 days in an average southern hemisphere autumn). During a typical southern hemisphere autumn winds stronger than >40kph (25mph) are expected on 3 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.
