2nd Beach Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to 2nd Beach, located 22 km away (14 miles). There are insufficient 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 2nd Beach blows from the SSE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at 2nd Beach. On the other hand, 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 5% of the time (2 days each April) and blows offshore 23% of the time (5 days in an average April). Over an average April wind stronger than >40kph (25mph) was expected for only a single days at 2nd Beach
