The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Happy Jacks, located 9 km away (6 miles). There are not enough 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 Happy Jacks blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Happy Jacks. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each May) and blows offshore just 11% of the time (3 days in an average May). During a typical May wind stronger than >40kph (25mph) was predicted for only a single days at Happy Jacks
