Estadísticas de Viento para Aramoana Spit, Promedio de Invierno desde 2006
This picture shows how commonly and how strongly the wind blows from different directions over a normal southern hemisphere winter. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aramoana Spit, located 29 km away (18 miles). There are not enough 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 dominant wind at Aramoana Spit blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aramoana Spit. By contrast, dominant spokes represent 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 winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (3 days each southern hemisphere winter) and blows offshore just 8% of the time (5 days in an average southern hemisphere winter). Over an average southern hemisphere winter winds stronger than >40kph (25mph) are expected on 2 days at Aramoana Spit
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.
