Dump Beach Wind Stats

The figure illustrates how often 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 darkest shade of blue strongest. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Dump Beach, located 53 km away (33 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 dominant wind at Dump Beach blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Dump Beach. Converseley, dominant spokes show favoured directions, and the more deep 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 (the lightest shade of blue) about 7% of the time (2 days each April) and blows offshore 25% of the time (5 days in an average April). Over an average April wind stronger than >40kph (25mph) was predicted for only a single days at Dump Beach
