San Miguel - Areias Wind Statistics, October averages since 2006
This chart illustrates how frequently and how strongly the wind blows from different directions through a typical October. The largest 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 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 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 dominant 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. On the other hand, dominant spokes illustrate 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 (pale blue) about 5% of the time (2 days each October) and blows offshore 23% of the time (7 days in an average October). In a typical October winds stronger than >40kph (25mph) are expected on 3 days 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.
