Aramoana Spit Wind Statistics, February averages since 2006
The graph describes how often and how strongly the wind blows from different directions through a typical February. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 2102 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 insufficient 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 most common 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. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average February, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each February) and blows offshore just 9% of the time (1 days in an average February). In a typical February 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.
