The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 2477 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anna Maria Key, located 26 km away (16 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
