Statistiques de Vent de Awakino River Mouth, moyennes sur Printemps depuis 2006
The graph describes how frequently and how strongly the wind blows from different directions over a normal southern hemisphere spring. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Awakino River Mouth, located 21 km away (13 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 dominant wind at Awakino River Mouth blows from the W. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Awakino River Mouth. 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 southern hemisphere spring, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (9 days each southern hemisphere spring) and blows offshore 23% of the time (4 days in an average southern hemisphere spring). Over an average southern hemisphere spring winds stronger than >40kph (25mph) are expected on 5 days at Awakino River Mouth
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.
