Statistiques de Vent de Ardnave Point and Bay (Islay), moyennes sur Novembre depuis 2006
This picture describes how often and how strongly the wind blows from different directions through a typical November. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 2387 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ardnave Point and Bay (Islay), located 18 km away (11 miles). There are insufficient 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 prevailing wind at Ardnave Point and Bay (Islay) blows from the W. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ardnave Point and Bay (Islay). Converseley, dominant spokes represent 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 November, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each November) and blows offshore just 37% of the time (6 days in an average November). In a typical November winds stronger than >40kph (25mph) are expected on 11 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.
