Battery Beach Wind Stats

The figure describes how frequently and how strongly the wind blows from different directions through a typical August. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 3574 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Battery Beach, located 20 km away (12 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Battery Beach blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Battery 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. Over an average August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each August) and blows offshore 21% of the time (7 days in an average August). In a typical August wind stronger than >40kph (25mph) was expected for only a single days at Battery Beach
