Statistiques de Vent de Ardnave Point and Bay (Islay), moyennes sur Février depuis 2006
The figure shows how often and how strongly the wind blows from different directions over a normal February. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2102 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Ardnave Point and Bay (Islay), located 18 km away (11 miles). There are not enough 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 Ardnave Point and Bay (Islay) blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Ardnave Point and Bay (Islay). Converseley, 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. During a typical February, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each February) and blows offshore just 44% of the time (8 days in an average February). Over an average February winds stronger than >40kph (25mph) are expected on 9 days at Ardnave Point and Bay (Islay)
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.
