Estadísticas de Viento para Avalon-North, Promedio de Primavera desde 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical southern hemisphere spring. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 7252 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. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Avalon-North blows from the E. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Avalon-North. Converseley, dominant spokes represent 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 spring, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (4 days each southern hemisphere spring) and blows offshore just 12% of the time (4 days in an average southern hemisphere spring). In a typical southern hemisphere spring winds exceeding >40kph (25mph) are not expected, but 4 have winds on the range 30-40 (19-25) 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.
