Santa Maria - Anjos Wind Statistics, February averages since 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical February. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by dark blue. It is based on 2102 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Santa Maria - Anjos, located 14 km away (9 miles). There are not enough recording stations world wide to use actual wind data. Without question 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 plot shows a nearly round shape, it means there is no strong bias in wind direction at Santa Maria - Anjos. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average February, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 6% of the time (2 days each February) and blows offshore 29% of the time (8 days in an average February). In a typical February winds stronger than >40kph (25mph) are expected on 5 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.
