Statistiques de Vent de Aberwystwyth Beach, moyennes sur Mai depuis 2006
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 deep blue strongest. It is based on 2197 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aberwystwyth Beach, located 29 km away (18 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 Aberwystwyth Beach 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 Aberwystwyth Beach. By contrast, dominant spokes illustrate 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 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 19% of the time (0 days in an average May). During a typical May wind stronger than >40kph (25mph) was expected for only a single days at Aberwystwyth Beach
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.
