Statistiques de Vent de Avalon Pier, moyennes sur Été depuis 2006
The figure describes how often and how strongly the wind blows from different directions through a typical northern hemisphere summer. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Avalon Pier, located 17 km away (11 miles). There are insufficient 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 Avalon Pier blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Avalon Pier. Converseley, 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (3 days each northern hemisphere summer) and blows offshore just 8% of the time (6 days in an average northern hemisphere summer). During a typical northern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 4 have winds on the range 30-40 (19-25) at Avalon Pier
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.
