Pai-Pai Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Pai-Pai, located 17 km away (11 miles). There are too few 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 most common wind at Pai-Pai blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Pai-Pai. 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 May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each May) and blows offshore 48% of the time (15 days in an average May). In a typical May winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Pai-Pai
