The graph describes how frequently and how strongly the wind blows from different directions through a typical February. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 1584 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Behakio, located 41 km away (25 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 dominant wind at Behakio blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Behakio. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average February, the model suggests that winds are light enough for the sea to be glassy (light blue) about 15% of the time (4 days each February) and blows offshore 31% of the time (9 days in an average February). In a typical February 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.
