what wind speed to kites fly at?
The best time to fly a kite is when the wind is between  4 and 12 miles-per-hour. If the wind is less, then most kites have problems flying. If the wind is more, then most kites will lose control. So watch the trees, bushes, flags and grass to know when the wind is just right. The other thing to watch for is wind turbulence. Turbulence is what happens when the wind gets bumpy.
