Estadísticas de Viento para Arrifana, Promedio de noviembre desde 2006
This chart shows how commonly and how strongly the wind blows from different directions over a normal November. 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 2387 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arrifana, located 26 km away (16 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 most common wind at Arrifana blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Arrifana. By contrast, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each November) and blows offshore 51% of the time (11 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 2 days at Arrifana
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.
