Statistiques de Vent de Diamond Head, moyennes sur Printemps depuis 2006

This chart illustrates how commonly and how strongly the wind blows from different directions through a typical southern hemisphere spring. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 8724 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Diamond Head, located 31 km away (19 miles). There are insufficient 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 Diamond Head blows from the E. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Diamond Head. 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 southern hemisphere spring, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (6 days each southern hemisphere spring) and blows offshore 15% of the time (14 days in an average southern hemisphere spring). In a typical southern hemisphere spring wind stronger than >40kph (25mph) was predicted for only a single days at Diamond Head

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.
