Does barometric pressure affect deer movement?
Yes. The clearest pattern in deer-movement studies is a spike in daylight activity when the barometer rises sharply after a low — typically the day a cold front clears out. Falling pressure into a storm and steady high pressure both correlate with reduced daylight movement.
Movement on the rising side of a high — when pressure crosses about 30.0 inHg on the way up — is some of the most reliable daylight activity hunters can plan. The trigger isn't the absolute number; it's the rate of change.
Steady high-pressure days produce the lowest observable movement, partly because clear sky and warm air also push activity to night. Pair pressure forecasts with the rut window for your state and the current mast picture, and pick sit days where the pressure is moving fast.
