The graph illustrates how often and how strongly the wind blows from different directions through a typical April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Battery Beach, located 20 km away (12 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 Battery Beach blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Battery Beach. On the other hand, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 14% of the time (4 days each April) and blows offshore 26% of the time (8 days in an average April). In a typical April wind stronger than >40kph (25mph) was predicted for only a single days at Battery Beach
