The Jetty Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions through a typical June. The biggest 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 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Jetty, located 37 km away (23 miles). There are insufficient 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 prevailing wind at The Jetty blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Jetty. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (3 days each June) and blows offshore 30% of the time (8 days in an average June). During a typical June wind stronger than >40kph (25mph) was predicted for only a single days at The Jetty
