Army Beach Wind Statistics, Winter averages since 2006
This chart shows how often and how strongly the wind blows from different directions over a normal northern hemisphere winter. The biggest 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 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Army Beach, located 32 km away (20 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 Army Beach blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Army Beach. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 17% of the time (15 days each northern hemisphere winter) and blows offshore 29% of the time (26 days in an average northern hemisphere winter). Over an average northern hemisphere winter winds stronger than >40kph (25mph) are expected on 2 days at Army Beach
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.
