Ahu Ahu Road Wind Statistics, October averages since 2006
The graph shows how commonly and how strongly the wind blows from different directions through a typical October. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ahu Ahu Road, located 17 km away (11 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Ahu Ahu Road blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Ahu Ahu Road. By contrast, dominant spokes illustrate 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 October, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (2 days each October) and blows offshore 18% of the time (6 days in an average October). In a typical October winds stronger than >40kph (25mph) are expected on 2 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.
