These studies provide some level of explanation for the relationship between weather and deer movement. Don't worry about the biological, environmental and other scientific factors if your only aim is to enjoy creation. Proponents argue that deer react instinctually to the impending weather and begin to feed in order to survive the possibility of hours (or days) of inactivity and/or limited food. Best pressure for deer hunting uk. Just as I was nearing the tree I intended to climb, I came face to face with a mature buck making a rub 15 yards away in a slough, but he saw me first. Making sure that you are there for the break in the storm is key to your whitetail success. Prior to a storm, looking for a falling barometer might also be a successful tactic. However, one weather variable in particular is often sighted as the most significant factor in whitetail deer movement: barometric pressure. How do you read barometric pressure for deer hunting? He has killed countless whitetails in his years as a biologist and hunter.
Barometric pressure changes indicate a storm is approaching and that temperatures are getting cooler. Regardless of weather conditions, there's going to be heightened deer activity.

While there are numerous aspects that continuously successful hunters take into account, barometric pressure is one of the most prevalent and important factors considered. During hunting season, many members of my squad, who usually care less about the weather, start reaching out for a personal forecast. Changes in barometric pressure in general are some of the best times to hunt. In addition, by spending a lot of time in the woods on days when deer are least active, hunters might be limiting their chances of harvesting deer, particularly older individuals with more experience dealing with hunters. It's also a game of decisions. When the barometric pressure is dropping, it means temperatures are getting colder and a storm is coming. Often, the deer that you've worked so hard to pattern completely change their behavior or seem to disappear altogether once you begin hunting them. Deer pack some robust natural weatherproofing and will still feed during rain. Deer Hunting by Weather Forecast.

It's a form of atmospheric updraft and is a result of uneven ground temperatures from solar radiation. While there are many factors that consistently successful hunters consider when making this determination, barometric pressure is one of the most common and influential variables taken into account. Simply, the less the better. The tendency of hunters to concentrate their hunting efforts on weekends, with much less time spent hunting throughout the rest of the week, appears to be a huge red flag to deer, indicating that they should shut down their movements until the storm passes. Environmental and biological factors aside, there are a few other key times to be in the deer woods. I've seen evidence that supports both sides. I've killed numerous deer (including nice bucks) right before a weather front pushed into the area. In addition to traveling less during daylight hours, deer tended to utilize progressively smaller areas throughout the weekend, but began moving more broadly across the landscape later in the week once hunting pressure had declined. In the evening, the deer will be drifting toward the feeding areas, so favor trails/funnels closer to food. In a study conducted in Maryland by North Carolina State University, low levels of hunting pressure had no noticeable effect on the behavior of adult bucks except for causing occasional, short-distance flights when deer entered the immediate proximity of a hunter. Its findings show that the most powerfully predictive weather condition is barometric pressure. "I don't do it much anymore because of fire dangers, but I like to release a smoke bomb in the woods, " he said. That means hunting downwind of the areas you're expecting the deer to wind up. Barometric pressure and deer movement.
An even bigger buck was with him, but out of archery range in the distance. Tips For Hunting Both Low and High Barometric System. These types of weather conditions strongly inhibit the movement of deer.

They sense the oncoming weather and tend to feed heavily just prior to its arrival, and if it lingers, just after its departure, too. Deer Response to Hunting. In terms of the rut, Perez's decades of personal observations fall in line with scientific research when it comes to weather's influence on this magical time of year.
Ardent barometric pressure watchers say if you really want to see some serious movement, head to your stand during the storm to capitalize on the increased deer movement that begins to happen right as the weather is breaking and the pressure is rising. While we may not be able to find a major change in movement statistically, a small 2-5% increase in movement, while not statistically significant, could be all we need to get that target buck to travel a bit further than his daily routine. The deer makes a move. But what I and many deer hunters care about is a slight edge that might result in a mature buck moving just a bit further or a few minutes earlier than normal.
