Assinie Wind Statistics, April averages since 2006
The figure describes how frequently and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Assinie, located 11 km away (7 miles). There are insufficient 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 Assinie blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Assinie. On the other hand, dominant spokes show 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 (pale blue) about 9% of the time (3 days each April) and blows offshore 9% of the time (3 days in an average April). Over an average April winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Assinie
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
