Rule for Practice

photo credit: matsubokkuri     It's never a good idea to practice in windy conditions, especially when the wind is blowing at your back.  

For right-handers, when the wind is blowing at your back from left to right, the tendency is to swing over the top of the ball (outside in).   This is to compensate for the wind direction, however, it creates a slice/pull swing.   When the wind is blowing from right to left just opposite is true.   The golfer will swing too much on the inside created  a hook/push swing path (inside out).

Practicing with the wind in your face isn't helpful either because  of the tendency  to punch the ball without taking a full swing.    The best rule of thumb is to  practice on windless days.
