Point Roadnight 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 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 Point Roadnight, located 29 km away (18 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 Point Roadnight blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Point Roadnight. Converseley, 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 0.1% of the time (0 days each May) and blows offshore just 4% of the time (1 days in an average May). During a typical May wind stronger than >40kph (25mph) was expected for only a single days at Point Roadnight
