Statistiques de Vent de Boston Bay, moyennes sur Septembre depuis 2006

This chart shows how often and how strongly the wind blows from different directions through a typical September. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2880 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Boston Bay, located 38 km away (24 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 dominant wind at Boston Bay blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Boston Bay. Converseley, 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 September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each September) and blows offshore 11% of the time (3 days in an average September). In a typical September winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Boston 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.
