Deer live and die by their noses. So all you have to do is keep the deer upwind of you, simple right? Unfortunately the wind is a fickle beast. It flows like water over the terrain. Anything that catches its path will cause it to swirl and twirl like water in a broken stream. If you are hunting on the leeward side of a mountain then the wind will swirl around like dervish, altering directions on a dime. Even sitting behind a small object can change the winds flow. Learning the wind and knowing the terrain are important skills for hunters to master, they go hand in hand. It can make for a very frustrating hunt when the wind seems to be swirling this way and that. Definitely not a time to sit still for long periods of time. You’ll notice the same thing happens when clouds roll in creating fog. Clouds make for turbulent winds. Turbulent winds do not mean your hunt is over. They just mean that your chances of catching animals unaware diminishes. You’ll never know if that wind will curl away from the nose of an unfortunate animal. Or if it will wind you, but not know where you are. To top all this off, you’ll need to master the thermals. The cool night air sinks into the valleys creating a flow of air cascading down the mountain sides. When the sun warms the air it will begin to rise, the thermal will shift upslope. This effect will strengthen the more pronounced the shift in temperatures. You will feel it strongest when the prevailing wind is calmer. All these factors work together to create the complete shifting wind picture for the area you are hunting. Knowing the terrain and how different winds affect it is one of those keys to effectively hunting an area. It’s a lot to learn, the first step is to pay attention to your surroundings, try to keep the wind in your face, and hunt well.
