North Jetty Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions over a normal November. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 2867 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to North Jetty, located 33 km away (21 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 most common wind at North Jetty blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at North Jetty. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (1 days each November) and blows offshore just 9% of the time (2 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 2 days at North Jetty
