Wind Stats
The figure describes how commonly and how strongly the wind blows from different directions over a normal April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3358 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Preston Beach, located 40 km away (25 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 Preston Beach blows from the E. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Preston Beach. Converseley, 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 April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 1.6% of the time (0 days each April) and blows offshore just 2.0% of the time (0 days in an average April). Over an average April wind stronger than >40kph (25mph) was predicted for only a single days at Preston Beach
