Vleesbaai Wind Stats

The graph illustrates how commonly and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Vleesbaai, located 24 km away (15 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 prevailing wind at Vleesbaai blows from the SSE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Vleesbaai. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from.

Over an average July wind stronger than >40kph (25mph) was forecast for only a single days at Vleesbaai
