Statistiques de Vent de Ala Moana Bowls, moyennes sur Toute l'Année depuis 2006
This picture illustrates how frequently and how strongly the wind blows from different directions over a normal year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 28044 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 too few 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 Ala Moana Bowls blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ala Moana Bowls. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical year, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (18 days each year) and blows offshore 14% of the time (51 days in an average year). Over an average year wind stronger than >40kph (25mph) was predicted for only a single days 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.
