Statistiques de Vent de Ackergill, moyennes sur Juillet depuis 2006
This chart shows how commonly and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ackergill, located 5 km away (3 miles). There are too few 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 most common wind at Ackergill blows from the N. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Ackergill. By contrast, dominant spokes show 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 July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each July) and blows offshore just 11% of the time (2 days in an average July). Over an average July wind stronger than >40kph (25mph) was expected for only a single days at Ackergill
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.
