Barometric Pressure

7 posts in this topic

How much does barometric pressure play in your decision to go fishing? My fishing buddy won't go out if it's a high pressure, say over 30.

When it's a low pressure he jumps at the chance.

Does it really make much of a difference? I've seen some other post about the tendencies etc. Just wondering what others think about it...

I will say that I find the fishing too be worse in high pressure, but the only thing that keeps me off the lake is not having the time to go.

This buddy of mine that won't fish in a high pressure uses an analogy of minnows in a plastic bag.

If you squeeze down on the bag, the minnows freeze and don't move- that's high pressure. After you release the minnows start moving again (low pressure)

Makes sense but not sure if it holds true for fish biting or more active...

Interesting test but I wonder about the validity of the result.

How hard do you have to squeeze the bag to raise the atmospheric pressure inside by 1" of mercury? The earth's barometric pressure doesn't change very much from high to low. The highest recorded sea level pressure ever recorded was 32.29" during an extremely cold air mass in Siberia. The lowest ever recorded at sea level was 25.69 in the eye of a typhoon over the pacific. Typical change is from about 29 in.Hg. to 31 in.Hg.

Watching the fish in our aquarium, I have never recognized any behavior change from one state to another.

Take this for what it is worth. I keep records on how I do fishing, date, time, pressure etc. I found a web site called weather underground On that site there is a button for history data or something similar.

I back checked the best days I had fishing and almost always it was when the pressure was dropping sharply.

I fish when ever I can...but I try extra hard to get out on the ice when I see the pressure dropping sharply. Very rarely (if ever) do I have a bad fishing day when the pressure is falling sharply. Sausage

I will not let the barro affect "IF" I go fishing. I let the barro affect, "How" I go fishing.

Deitz has a good line and I do change how I fish with the barometer as well. However I have not gone fishing many times when the pressure is very high, especially for muskies. And those times when there's a storm coming up and it starts to plummet I do what I can to get on the water..

    • Thanks Rebel, very good answer.  I've been keeping track of the pressure for a week, now. 
    • Hey Rebel, what do you consider low and high pressure?  Perhaps a stupid question, but I just got a weather station so now I can start tracking barometric pressure. Right now the numbers don't mean much to me, been around 28-29% in the south metro the past few day and I don't know if that's low, high or middle.
    • Low pressure signals a front moving in, (Bad weather, wind may be  from the east or north) which usually puts them "on the feed", can have some hot and fast action. Likewise, a swing in the other direction, a high pressure system , (wind from the west or south) which signals clear skies and sunny weather, may do the same. The key to me, anyway, seems to be hitting it just as either front moves in. An extended low or long high may result in poor fishing. Remember the old adage, which also has to so with the pressure: "Wind from the east; fish bite the least...wind from the north , the fisherman goes not forth, wind from the south, blows the bait in the fish's mouth; wind from the west, is when the fishing is best". 
    • Those trumpers sure know how to keep things classy.
    • Is it true, the lower the pressure, the bite gets hot? Or the higher the barometric pressure the fish slow down on biting? 
    • Is that like saying "the lights are on, but nobodies  home.?
    • Newsie's where reporting on how the lights are on in the white house at 5am...   "First time in a long long time.."    
    • Beautiful!!! Can I ask what your dry brine for the side pork was?
    • Don't forget to get your Dihydrogen Monoxide detector as well!!! That's what we really need to be worried about!! Especially on and around lakes!
