From what I've read and seen, the rut usually iscontrolled by the amount of light per day that affects the pituitary gland of deer; it causes the does to come into heat and the buck to "get rutty". That's why they have a rut in Florida as well as other, colder states. Shorter days = less light = rut.
But having said that, it also seems like colder weather will get the deer to moving more - and that may have more to do with their increased need for food than anything else. But as the does move around more, the bucks also move around more - so in my experience, I have seen more deer being more active when the weather cools down than when it's warm.
Don't worry about getting that first deer - spend time in the woods and apply the knowledge you can get from this and other forums, and it will happen. A guy I was hunting with last week made a very profound observation: "When you are out in the woods with your rifle, you significantly increase yourchances ofgetting adeer."
Good Luck!
