Statistiques de Vent de All Day Bay, moyennes sur Août depuis 2006
The figure shows how commonly and how strongly the wind blows from different directions through a typical August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to All Day Bay, located 34 km away (21 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at All Day Bay blows from the SSE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at All Day Bay. By contrast, dominant spokes show 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 August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 12% of the time (4 days each August) and blows offshore 39% of the time (12 days in an average August). In a typical August winds stronger than >40kph (25mph) are expected on 2 days at All Day Bay
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.
