Aropaonui Wind Statistics, Summer averages since 2006
This image shows how commonly and how strongly the wind blows from different directions through a typical southern hemisphere summer. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aropaonui, located 24 km away (15 miles). There are too few 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 Aropaonui blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Aropaonui. 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 southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 21% of the time (19 days each southern hemisphere summer) and blows offshore 41% of the time (32 days in an average southern hemisphere summer). In a typical southern hemisphere summer wind stronger than >40kph (25mph) was expected for only a single days at Aropaonui
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.
