Shelly Beach Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions over a normal May. The longest 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 3422 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Shelly Beach, located 52 km away (32 miles). There are insufficient 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 Shelly Beach blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Shelly Beach. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 12% of the time (4 days each May) and blows offshore 51% of the time (8 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 6 days at Shelly Beach
