San Miguel - Areias Wind Statistics, August averages since 2006
The figure shows how often and how strongly the wind blows from different directions over a normal August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to San Miguel - Areias, located 21 km away (13 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 San Miguel - Areias blows from the NNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at San Miguel - Areias. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical August, the model suggests that winds are light enough for the sea to be glassy (light blue) about 8% of the time (2 days each August) and blows offshore 18% of the time (2 days in an average August). Over an average August winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at San Miguel - Areias
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.
