Praia Grande Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions over a normal November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Praia Grande, located 46 km away (29 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 dominant wind at Praia Grande blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Praia Grande. By contrast, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (light blue) about 22% of the time (7 days each November) and blows offshore 29% of the time (9 days in an average November). Over an average November winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Praia Grande
