‘You don’t need a weather man to know which way the wind blows’

Wind Data 27 March 2012

But this site will show you the wind in motion.

Surface wind data comes from the National Digital Forecast Database. These are near-term forecasts, revised once per hour. So what you’re seeing is a living portrait. (See the NDFD site for precise details; our timestamp shows time of download.) And for those of you chasing top wind speed, note that maximum speed may occur over lakes or just offshore.

There is also a historical gallery.
