Anna Bay-Morna Point Wind Statistieken, December gemiddelde vanaf 2006
This image illustrates how often and how strongly the wind blows from different directions over a normal December. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 2457 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. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing 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. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical December, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (2 days each December) and blows offshore 47% of the time (9 days in an average December). Over an average December wind stronger than >40kph (25mph) was expected 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.
