Armadale Bay Wind Statistics, January averages since 2006
This chart describes how commonly and how strongly the wind blows from different directions over a normal January. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2372 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Armadale Bay, located 50 km away (31 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 prevailing wind at Armadale Bay blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Armadale Bay. On the other hand, 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 January, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 2% of the time (1 days each January) and blows offshore just 41% of the time (13 days in an average January). Over an average January winds stronger than >40kph (25mph) are expected on 13 days at Armadale 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.
