Cape Cod Wind displays the current wind speed and direction via wind barbs on Cape Cod and the Islands. Hovering the mouse over a barb will reveal more detailed information, including the speed to the nearest mph, direction to the nearest degree, and the last time NOAA updated the sensor. Perfect for windsurfers and sailors who live on the Cape.
If you don't know how to read wind barbs, I have written a quick tutorial located at
