Myrtle Beach - Pier 14 Wind Statistics, September averages since 2006
The graph describes how often and how strongly the wind blows from different directions over a normal September. The largest 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 deep blue. It is based on 2400 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Myrtle Beach - Pier 14, located 31 km away (19 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 dominant wind at Myrtle Beach - Pier 14 blows from the ESE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Myrtle Beach - Pier 14. 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 September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 17% of the time (5 days each September) and blows offshore 29% of the time (6 days in an average September). Over an average September winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Myrtle Beach - Pier 14
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.
