Manhattan 26th street Wind Statistics, Autumn averages since 2006
This chart shows how commonly and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The biggest 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 6516 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Manhattan 26th street, located 43 km away (27 miles). There are not enough 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 most common wind at Manhattan 26th street blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Manhattan 26th street. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 23% of the time (21 days each northern hemisphere autumn) and blows offshore 37% of the time (32 days in an average northern hemisphere autumn). In a typical northern hemisphere autumn winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Manhattan 26th 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.
