Estadísticas de Viento para Arrieta, Promedio de agosto desde 2006
The graph illustrates how commonly and how strongly the wind blows from different directions through a typical August. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arrieta, located 41 km away (25 miles). There are not enough 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 Arrieta blows from the N. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Arrieta. By contrast, dominant spokes illustrate 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 August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0.5% of the time (0 days each August) and blows offshore just 4% of the time (0 days in an average August). During a typical August winds stronger than >40kph (25mph) are expected on 2 days at Arrieta
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.
