Keurbooms Wind Stats

The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Keurbooms, located 54 km away (34 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 Keurbooms blows from the SSE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Keurbooms. 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. Over an average May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 0.9% of the time (0 days each May) and blows offshore just 4% of the time (1 days in an average May). In a typical May wind stronger than >40kph (25mph) was forecast for only a single days at Keurbooms
