The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Winchesteer Bay/Umpqua Jetty, located 30 km away (19 miles). There are too few 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.
