The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 1920 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Myrtle Beach (The Yachtsman Pier), located 31 km away (19 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 prevailing wind at Myrtle Beach (The Yachtsman Pier) blows from the ESE.
