Petit Port Wind Stats

This picture shows how often and how strongly the wind blows from different directions through a typical May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3192 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Petit Port, located 40 km away (25 miles). There are insufficient 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 prevailing wind at Petit Port blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Petit Port. 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 (light blue) about 7% of the time (2 days each May) and blows offshore 22% of the time (6 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 2 days at Petit Port
