The figure illustrates how commonly and how strongly the wind blows from different directions through a typical September. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue strongest. It is based on 2400 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 not enough recording stations world wide to use actual wind data. Invevitably 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).

During a typical September winds stronger than >40kph (25mph) are expected on 6 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.
