Manhattan 26th street Wind Statistics, Summer averages since 2006
The figure illustrates how commonly and how strongly the wind blows from different directions over a normal northern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 5802 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 insufficient 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 prevailing wind at Manhattan 26th street blows from the WSW. If the rose plot shows a nearly round shape, 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 the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 12% of the time (11 days each northern hemisphere summer) and blows offshore 14% of the time (13 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 0 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.
