Santa Maria - Anjos Wind Statistieken, Zomer gemiddelde vanaf 2006
The rose diagram illustrates how often and how strongly the wind blows from different directions over a normal northern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 7266 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 not enough recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Santa Maria - Anjos blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Santa Maria - Anjos. 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (5 days each northern hemisphere summer) and blows offshore 11% of the time (10 days in an average northern hemisphere summer). Over an average northern hemisphere summer wind stronger than >40kph (25mph) was expected for only a single 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.
