Kia Island Reef Wind Stats

This chart describes how commonly 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 dark blue strongest. It is based on 3582 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Kia Island Reef, located 21 km away (13 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 Kia Island Reef blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Kia Island Reef. 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 (light blue) about 4% of the time (1 days each August) and blows offshore just 9% of the time (3 days in an average August). During a typical August winds exceeding >40kph (25mph) are not expected, but 4 have winds on the range 30-40 (19-25) at Kia Island Reef
