Aramoana Spit Wind Statistieken, December gemiddelde vanaf 2006
This image shows how commonly and how strongly the wind blows from different directions over a normal December. 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 2457 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. 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 graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aramoana Spit. On the other hand, 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 December, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each December) and blows offshore just 12% of the time (2 days in an average December). Over an average December wind stronger than >40kph (25mph) was expected for only a single 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.
