Estadísticas de Viento para Avalon-North, Promedio de Verano desde 2006
The graph shows how frequently and how strongly the wind blows from different directions through a typical southern hemisphere summer. 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 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Avalon-North, located 21 km away (13 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 Avalon-North blows from the E. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Avalon-North. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (6 days each southern hemisphere summer) and blows offshore 11% of the time (5 days in an average southern hemisphere summer). During a typical southern hemisphere summer wind stronger than >40kph (25mph) was expected for only a single days at Avalon-North
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.
