Santa Maria - Anjos Wind Statistics, November averages since 2006
The figure illustrates how often and how strongly the wind blows from different directions over a normal November. The longest 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 showing the strongest winds. It is based on 2387 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Santa Maria - Anjos, located 14 km away (9 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 prevailing wind at Santa Maria - Anjos blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Santa Maria - Anjos. Converseley, dominant spokes represent favoured directions, and the more deep 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 4% of the time (1 days each November) and blows offshore just 16% of the time (5 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 3 days at Santa Maria - Anjos
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.
