Red Island Wind Stats

This chart shows how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Red Island, located 17 km away (11 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Red Island blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Red Island. 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. During a typical April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each April) and blows offshore 35% of the time (5 days in an average April). Over an average April wind stronger than >40kph (25mph) was predicted for only a single days at Red Island
