Pai-Pai Wind Stats

The figure describes how often 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 suggests the strength, with the darkest shade of blue strongest. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Pai-Pai, located 17 km away (11 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 Pai-Pai blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Pai-Pai. By contrast, dominant spokes represent 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 3% of the time (1 days each August) and blows offshore just 37% of the time (11 days in an average August). In a typical August wind stronger than >40kph (25mph) was predicted for only a single days at Pai-Pai
