Ponta Preta Wind Stats

The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Ponta Preta, located 13 km away (8 miles). There are too few 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 Ponta Preta blows from the NNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Ponta Preta. By contrast, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 0.3% of the time (0 days each April) and blows offshore just 22% of the time (7 days in an average April). Over an average April winds exceeding >40kph (25mph) are not expected, but 5 have winds on the range 30-40 (19-25) at Ponta Preta
