I prefer to hunt in wind 5-10mph. A STEADY wind. This gives me more opportunity to move, and cover up sound. Nothing like trying to draw on a deer with no wind and absolute silence. The brush of your whiskers on your coat sound like buzz saw.

I've hunted in strong winds and have found deer movement to decrease, but the rest of the weather played a role as well (was it raining? clear? etc..). Peak rut is the exception though. Bucks tend to lose control of their minds.

I don't see wind as being a problem unless it's a swirling, direction changing wind. Not saying don't hunt, but two things happen in this type of wind: the deer or more on edge because sound is coming from different directions constantly with the shifting wind, and they are far more likely to pick your scent up when the wind is all over the place.
