Haardebaai Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions through a typical June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Haardebaai, located 21 km away (13 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 prevailing wind at Haardebaai blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Haardebaai. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 11% of the time (3 days each June) and blows offshore 58% of the time (15 days in an average June). In a typical June winds stronger than >40kph (25mph) are expected on 4 days at Haardebaai
