Pontal Wind Stats

This image shows how often and how strongly the wind blows from different directions through a typical May. 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 the darkest shade of blue. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Pontal, located 37 km away (23 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 Pontal blows from the NNE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Pontal. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each May) and blows offshore just 4% of the time (1 days in an average May). In a typical May winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Pontal
