Statistiques de Vent de Arugam Bay, moyennes sur Octobre depuis 2006
This picture illustrates how frequently and how strongly the wind blows from different directions through a typical October. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arugam Bay, located 42 km away (26 miles). There are insufficient 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 Arugam Bay blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Arugam Bay. On the other hand, 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 October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 21% of the time (7 days each October) and blows offshore 26% of the time (8 days in an average October). During a typical October winds stronger than >40kph (25mph) are expected on 2 days at Arugam Bay
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.
