Prainha Wind Stats

The graph illustrates how commonly and how strongly the wind blows from different directions over a normal June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Prainha, located 26 km away (16 miles). There are too few 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 Prainha blows from the SSE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Prainha. On the other hand, 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 June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 15% of the time (4 days each June) and blows offshore 25% of the time (4 days in an average June). Over an average June winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Prainha
