Aropaonui Wind Statistics, Ottobre averages since 2006
This image describes how often and how strongly the wind blows from different directions over a normal October. The largest 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 showing the strongest winds. It is based on 2477 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. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Aropaonui blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aropaonui. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical October, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 18% of the time (6 days each October) and blows offshore 45% of the time (11 days in an average October). Over an average October winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) 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.
