The South Jetty Wind Stats

The figure describes how frequently and how strongly the wind blows from different directions through a typical April. The largest 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 3359 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to The South Jetty, located 36 km away (22 miles). There are too few 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 most common wind at The South Jetty blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at The South Jetty. 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 April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each April) and blows offshore 30% of the time (8 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 3 days at The South Jetty
