Agucadoura Wind Statistics, March averages since 2006
This image shows how often and how strongly the wind blows from different directions through a typical March. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Agucadoura, located 19 km away (12 miles). There are too few 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 prevailing wind at Agucadoura blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Agucadoura. On the other hand, 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 March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 18% of the time (6 days each March) and blows offshore 40% of the time (12 days in an average March). In a typical March wind stronger than >40kph (25mph) was forecast for only a single days at Agucadoura
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.
