Most people will say that deer don't move in the high winds, which often I have found to be true. However, I have also been out during very windy days and saw plenty.............and my buddy saw a really nice buck on a farm we hunt on maybe the windiest day I have ever hunted.

There must be another factor involved as just high aren't enough to stop them IMO..........I believe the motion of the brush is not their main source of irritation during high wind but if it is windy and really noisy with limbs falling and cracking then I would say they won't be to happy. Not being able to hear makes them less comfortable then not being able to see IMO.
