Jones Beach State Park Wind Statistics, Spring averages since 2006
The rose diagram describes how often and how strongly the wind blows from different directions through a typical northern hemisphere spring. The largest 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 6579 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Jones Beach State Park, located 10 km away (6 miles). There are insufficient 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 dominant wind at Jones Beach State Park blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Jones Beach State Park. 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. Over an average northern hemisphere spring, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (6 days each northern hemisphere spring) and blows offshore 32% of the time (25 days in an average northern hemisphere spring). During a typical northern hemisphere spring winds stronger than >40kph (25mph) are expected on 5 days at Jones Beach State Park
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.
