This image illustrates how frequently and how strongly the wind blows from different directions over a normal year. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 20060 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ocean City 8th Street, located 31 km away (19 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 Ocean City 8th Street blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ocean City 8th Street. On the other hand, 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 year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (26 days each year) and blows offshore 29% of the time (99 days in an average year). Over an average year winds stronger than >40kph (25mph) are expected on 22 days at Ocean City 8th Street
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.
