I hate bow hunting in heavy or even kind of heavy winds. IMO I definitely think it affects deer movement. High winds and or swirling winds can throw a deer's sense of sense into overload. The threat might be a couple hundred yards away but with high winds it might seem like it is right on top of them. I would also agree with meetseeker, I would rather pass on a good spot on a windy day if for nothing else, to keep pressure out. On the flip slide, if you have a nice bottom to hunt on a windy day with good food/cover I think you'll have a good chance of filling a tag.
