This picture shows how frequently and how strongly the wind blows from different directions through a typical March. The biggest 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 2220 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. 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 WNW. 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). By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (2 days each March) and blows offshore 40% of the time (7 days in an average March). In a typical March 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.
