Deer are sensitive to changes in barometric pressure, and their activity levels can be influenced by these changes. While there is no definitive best barometric pressure for deer hunting, many hunters believe that deer movement increases when the barometric pressure is between 29.90 and 30.30 inches of mercury (inHg).
Deer activity often increases just before and after a significant change in barometric pressure. These changes typically occur before a storm or a change in weather patterns. During periods of high pressure, deer may feel more secure and be more inclined to move and feed.
As a bow hunter, it’s a good idea to monitor weather forecasts and pay attention to barometric pressure changes. Hunting just before or after a significant change in pressure, such as before a storm or during a period of stable high pressure, may increase your chances of encountering active deer.
However, it’s important to remember that other factors such as temperature, wind, and time of day also play a role in deer movement. Scouting your hunting area, understanding local deer behavior, and considering various environmental factors will help you make more informed decisions and increase your chances of a successful hunt.
