Azurara Wind Statistics, Outubro averages since 2006
This picture shows how commonly and how strongly the wind blows from different directions through a typical October. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Azurara, located 28 km away (17 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 dominant wind at Azurara blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Azurara. On the other hand, dominant spokes represent 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 October, the model suggests that winds are light enough for the sea to be glassy (light blue) about 22% of the time (7 days each October) and blows offshore 41% of the time (13 days in an average October). During a typical October wind stronger than >40kph (25mph) was expected for only a single days at Azurara
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.
