Statistiques de Vent de Anse Bertrand, moyennes sur Hiver depuis 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical northern hemisphere winter. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anse Bertrand, located 30 km away (19 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 most common wind at Anse Bertrand 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 Anse Bertrand. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (light blue) about 2% of the time (2 days each northern hemisphere winter) and blows offshore just 26% of the time (2 days in an average northern hemisphere winter). During a typical northern hemisphere winter wind stronger than >40kph (25mph) was expected for only a single days at Anse Bertrand
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
