Statistiques de Vent de Agnes Waters, moyennes sur Février depuis 2006
The graph describes how commonly and how strongly the wind blows from different directions over a normal February. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2102 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Agnes Waters, located 27 km away (17 miles). There are too few 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 Agnes Waters blows from the ENE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Agnes Waters. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical February, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each February) and blows offshore just 5% of the time (1 days in an average February). Over an average February winds stronger than >40kph (25mph) are expected on 2 days at Agnes Waters
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.
