81st Street Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions over a normal May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to 81st Street, located 45 km away (28 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at 81st Street blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at 81st Street. Converseley, 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 May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (2 days each May) and blows offshore 37% of the time (11 days in an average May). Over an average May wind stronger than >40kph (25mph) was predicted for only a single days at 81st Street
