Peak Rock Wind Stats

The figure describes how commonly and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 2944 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Peak Rock, located 8 km away (5 miles). There are too few 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 most common wind at Peak Rock blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Peak Rock. On the other hand, dominant spokes represent favoured directions, and the more dark 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 (light blue) about 12% of the time (4 days each May) and blows offshore 53% of the time (7 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 3 days at Peak Rock
