Banzai Wind Statistics, All Year averages since 2006
The rose diagram illustrates how often 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 the darkest shade of blue strongest. It is based on 28044 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Banzai, located 12 km away (7 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Banzai blows from the SSE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Banzai. By contrast, dominant spokes illustrate favoured directions, and the more deep 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 9% of the time (33 days each year) and blows offshore 27% of the time (95 days in an average year). In a typical year winds stronger than >40kph (25mph) are expected on 5 days at Banzai
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.
