Surfies Point Wind Statistics, All Year averages since 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 23151 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Surfies Point, located 24 km away (15 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 Surfies Point blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Surfies Point. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (29 days each year) and blows offshore 23% of the time (29 days in an average year). In a typical year winds stronger than >40kph (25mph) are expected on 15 days at Surfies Point
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
