Ann Street Peaks Wind Statistics, Março averages since 2006
This chart illustrates how commonly and how strongly the wind blows from different directions through a typical March. The biggest 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 strongest. It is based on 2220 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. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Ann Street Peaks blows from the ESE. If the rose diagram shows a close to circular outline, 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 the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (2 days each March) and blows offshore 11% of the time (4 days in an average March). During a typical March winds stronger than >40kph (25mph) are expected on 3 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.
