Nags Head Pier Wind Stats

The figure describes how frequently and how strongly the wind blows from different directions through a typical May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Nags Head Pier, located 12 km away (7 miles). There are too few 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 prevailing wind at Nags Head Pier blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Nags Head Pier. By contrast, 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 May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each May) and blows offshore just 13% of the time (4 days in an average May). During a typical May wind stronger than >40kph (25mph) was expected for only a single days at Nags Head Pier
