Once a boomerang leaves your hand you have no control over it. Because a boomerang flies in a curved path, it is hard for a casual by-stander to anticipate which way it is going to go. Please keep safety in mind. Throwing Weather A nice, warm day with little or no breeze is almost ideal for boomeranging. Some boomerangs will not return in a dead calm.
Higher winds accommodate heavier boomerangs and different throwing techniques.
Gusting winds, or winds that change direction rapidly could cause you to lose control of your boomerang and should be avoided until you have some experience. An unfinished or poorly sealed boomerang will swell with moisture, possibly cracking the remaining finish or warping the boomerang itself. Also, throwing with snow on the ground is one of the best ways to lose a boomerang. You may be able to come back in the spring and find it, but chances are you won't. If you do find it, it will most likely be swollen to the size of your arm or shredded by the Park District mower.
