Statistiques de Vent de Aropaonui, moyennes sur Juin depuis 2006
This image illustrates how often and how strongly the wind blows from different directions through a typical June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2306 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 insufficient 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 most common wind at Aropaonui blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aropaonui. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each June) and blows offshore 46% of the time (13 days in an average June). In a typical June wind stronger than >40kph (25mph) was forecast 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.
