Praia Grande Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical October. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 3471 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Praia Grande, located 21 km away (13 miles). There are not enough 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 dominant wind at Praia Grande blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Praia Grande. On the other hand, dominant spokes represent favoured directions, and the more dark 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 (light blue) about 16% of the time (5 days each October) and blows offshore 31% of the time (10 days in an average October). During a typical October wind stronger than >40kph (25mph) was predicted for only a single days at Praia Grande
