Ala Moana Bowls Wind Statistics, June averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions over a normal June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ala Moana Bowls, located 35 km away (22 miles). There are not enough 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 most common wind at Ala Moana Bowls blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Ala Moana Bowls. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each June) and blows offshore 22% of the time (7 days in an average June). Over an average June winds exceeding >40kph (25mph) are not expected, but 4 have winds on the range 30-40 (19-25) at Ala Moana Bowls
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.
