New Jetty Wind Stats

This picture describes how frequently and how strongly the wind blows from different directions through a typical April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to New Jetty, located 47 km away (29 miles). There are insufficient recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at New Jetty blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at New Jetty. On the other hand, dominant spokes represent favoured directions, and the more dark 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 (the lightest shade of blue) about 14% of the time (4 days each April) and blows offshore 19% of the time (6 days in an average April). During a typical April wind stronger than >40kph (25mph) was forecast for only a single days at New Jetty
