San Miguel - Areias Wind Statistieken, September gemiddelde vanaf 2006
This image illustrates how frequently and how strongly the wind blows from different directions over a normal September. The biggest 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 2400 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 most common wind at San Miguel - Areias blows from the NNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at San Miguel - Areias.

Over an average September wind stronger than >40kph (25mph) was forecast for only a single 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.
