Statistiques de Vent de Ann Street Peaks, moyennes sur Mai depuis 2006
This image shows how frequently and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 2200 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Ann Street Peaks, located 45 km away (28 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 most common wind at Ann Street Peaks blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Ann Street Peaks. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 9% of the time (3 days each May) and blows offshore 25% of the time (7 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Ann Street Peaks
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.
