This picture describes how commonly and how strongly the wind blows from different directions over a normal September. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 1680 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Behakio, located 41 km away (25 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 prevailing wind at Behakio blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Behakio. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 14% of the time (4 days each September) and blows offshore 26% of the time (8 days in an average September). Over an average September winds stronger than >40kph (25mph) are expected on 2 days at Behakio
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.
