Estadísticas de Viento para Aramoana Spit, Promedio de mayo desde 2006
The figure shows how commonly and how strongly the wind blows from different directions through a typical May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aramoana Spit, located 29 km away (18 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 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. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each May) and blows offshore just 10% of the time (2 days in an average May). During a typical May winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) 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.
