Pernambuco Wind Stats

This picture shows how commonly and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 3192 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Pernambuco, located 19 km away (12 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 most common wind at Pernambuco blows from the SSE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Pernambuco. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 27% of the time (8 days each May) and blows offshore 48% of the time (15 days in an average May). Over an average May winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Pernambuco
