Wind Stats
This picture describes how frequently and how strongly the wind blows from different directions over a normal May. 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 3422 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to St Jean de Monts, located 31 km away (19 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 St Jean de Monts blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at St Jean de Monts. On the other hand, dominant spokes show favoured directions, and the more dark 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 9% of the time (3 days each May) and blows offshore 39% of the time (11 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at St Jean de Monts
