Anawhata Road (Oaonui) Wind Statistics, All Year averages since 2006
This picture illustrates how commonly and how strongly the wind blows from different directions over a normal year. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 28044 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anawhata Road (Oaonui), located 27 km away (17 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Anawhata Road (Oaonui) blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Anawhata Road (Oaonui). 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. During a typical year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (26 days each year) and blows offshore 19% of the time (69 days in an average year). Over an average year winds stronger than >40kph (25mph) are expected on 36 days at Anawhata Road (Oaonui)
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.
