The change in barometric pressure greatly effects deer movement. It triggers a sense in deer the need to feed due to a coming weather change. A falling barometer means a stormfront is coming. The barometer then stays low as the stormfront is present. As the stormfront moves out the barometer rises until the front has passed and levels out at a steady high barometer-meaning nice weather. The best time to hunt is the falling barometer because animals feel the need to feed before the storm. The next best time is when the barometer starts to rise signifying the stormfront has passed, again triggering deer to get up and feed. A steady high barometer is the next followed lastly by a steady low meaning the middle of the storm. I am a big believer in hunting by barometer movement. You can bet when the barometer is about to fall i will be hunting!!
