Cap Blanc Nez Wind Stats

The figure illustrates how commonly 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 dark blue strongest. It is based on 3192 NWW3 forecasts of wind since since 2008, at 3hr intervals, for the closest NWW3 model node to Cap Blanc Nez, located 17 km away (11 miles). There are not enough 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 most common wind at Cap Blanc Nez blows from the NNE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Cap Blanc Nez. 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 (pale blue) about 8% of the time (2 days each May) and blows offshore 15% of the time (2 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Cap Blanc Nez
