Ahu Ahu Road Wind Statistics, January averages since 2006
This picture shows how often and how strongly the wind blows from different directions through a typical January. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue strongest. It is based on 2372 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Ahu Ahu Road, located 17 km away (11 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 prevailing wind at Ahu Ahu Road blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Ahu Ahu Road. On the other hand, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each January) and blows offshore 28% of the time (9 days in an average January). During a typical January wind stronger than >40kph (25mph) was forecast for only a single days at Ahu Ahu Road
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.
