Video transcript

Barometric pressure is one of the most reliable movement triggers we can measure. Whitetails feel pressure changes long before you see the weather. Deer tend to move best when pressure is high and steady, roughly thirty inches of mercury and above, and again during the sharp rise right after a front clears. A fast falling barometer ahead of a storm often triggers a heavy feeding push, and then movement shuts down while the storm sits on you. Best Hunting Time tracks hourly pressure and its trend, and flags those rising and falling windows for your location.
