Statistiques de Vent de Anawhata Road (Oaonui), moyennes sur Été depuis 2006
The figure shows how frequently and how strongly the wind blows from different directions through a typical southern hemisphere summer. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests 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 Anawhata Road (Oaonui), located 27 km away (17 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 dominant wind at Anawhata Road (Oaonui) blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anawhata Road (Oaonui). On the other hand, dominant spokes illustrate favoured directions, and the more dark 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 8% of the time (7 days each southern hemisphere summer) and blows offshore 18% of the time (17 days in an average southern hemisphere summer). During a typical southern hemisphere summer winds stronger than >40kph (25mph) are expected on 5 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.
