Number's for deer I do not know. But if you understand BP you know that when the number's drop that means weather is moving in as in rain/snow/sleet all that. When the numbers go up as in high pressure pushing everything up that means your gona have clearish skie's and good weather. So when the number's drop I would expect to see a lot more movement due to the storm or bad weather coming in. Hope that answer's your question some sure someone else with a little better knowledge will chime in soon after me.
Agree... From what I have heard, falling pressure means changing weather from good to bad and deer try to feed.. especially where it snows where it is difficult to find food under a foot of snow.. Still waiting for it to snow in Florida.. LOL
"I have collected barometric pressure data from around the country for years through log book entries from trail cameras, hunters and private studies. The results are clear and indisputable. Deer like a pressure above 30.00 in. And if you want to see bucks, the ratio of bucks to does sighted when the pressure is between 30.00 – 30.40 is a staggering 1 to 1! When it drops and is between 29.8 and 30.00 there were a third as many deer spotted and with that figure your chances of seeing a buck dropps to 1 in 3. There is a sweet spot within the pressure scale that I have found and it seems to be at 30.20 to 30.30. There will also be a difference in sightings depending on if the pressure is rising or falling. Rising pressure right before its peak is best. "
if your in in the northern Midwest region just look at the weather and look for cold fronts moving in. during the winter months and the late archery season I just look for snow storms and go out the night before and whala there every where. Barometric pressure. Whitetail deer will increase their activities before and after weather fronts. They will feed most when the pressure is between 29.88 - 30.29 in.The sweet spot within the pressure scale, it has been found is at 30.20 to 30.30.There will also be a difference in sightings depending on if the pressure is rising or falling. Rising pressure right before its peak is best. Whitetails are most active right before rain or snow storms as well as just after them. Low barometric pressure will reduce deer activity. A lot of these high pressure points will come with wind.This is why so many trophies are taken right after sustained high winds +30mph have died down. North winds(NE TO NW) seem to bring the highest barometer readings. This is why many of our best stands and hunts are in conjunction with winds from these directions. Air temperature. This has a big affect on deer activity during daylight hours. Deer will be most active when the air temperature is between 25-35 degrees F.( -3C to -1C ). High winds. Deer activity is greatly reduced when winds are consistently above 10 m.p.h ( 16 km/h ) throughout the day. NW wind will bring cooler temperatures and higher barametric pressure, both key factors in good deer movement. The least desirable wind directions are SW or south which bring above average temperatures and low barametric pressures. When the wind speed drops from at least 30mph to 10mph, deer will be on the move. Many Pope and Young trophys where taken after a wind drop such as this. Humidity. A whitetail smells best when the humidity is between 20% to 80%. If it is extremely dry, raining or snowing, a whitetails ability to smell is decreased.
Yes inHg means "inches of mercury." It's just a unit of measure for pressure. But it is also used as just "inches."
