Shelley Beach Wind Stats

This picture shows how commonly and how strongly the wind blows from different directions over a normal September. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Shelley Beach, located 16 km away (10 miles). There are not enough 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 dominant wind at Shelley Beach blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Shelley Beach. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each September) and blows offshore 35% of the time (10 days in an average September). Over an average September wind stronger than >40kph (25mph) was predicted for only a single days at Shelley Beach
