Estadísticas de Viento para Arrieta, Promedio de Verano desde 2006
The rose diagram shows how frequently 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 strongest. It is based on 7266 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 insufficient recording stations world wide to use actual wind data. No doubt 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 graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Arrieta. By contrast, 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.5% of the time (1 days each northern hemisphere summer) and blows offshore just 9% of the time (0 days in an average northern hemisphere summer). During a typical northern hemisphere summer winds stronger than >40kph (25mph) are expected on 5 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.
