Mauvaise Greve Wind Stats

The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mauvaise Greve, located 35 km away (22 miles). There are not enough 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 dominant wind at Mauvaise Greve blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Mauvaise Greve. By contrast, 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. Over an average July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each July) and blows offshore 23% of the time (7 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 2 days at Mauvaise Greve
