How Does Barometric Pressure Effect Fishing

[Chuck7]

As a general guideline, think of 30 inHg (1016 millibar) as being a normal level. World records vary from a high pressure of 32.0 inHg in Siberia to 25.7 inHg during a typhoon (both readings are off the scale of most barometers). For the US, extreme levels can be considered as 30.5 inHg and 28.5 inHg. When it comes to fishing, a change of just +/- 0.02 inHg from normal is enough to effect their feeding habits.
It is important, however, to note that the effects of barometric pressure is greater in fresh and shallow waters, than it is in deeper waters. This is probably due to the fact that the pressure of water is so much greater in deeper waters making the air pressure above it no longer having any significance.
Some general rules regarding barometric pressure are:


High..Clear skies...Fish slow down, find cover or go to deeper waters.
Slow down lures and use baits more attractive to fish. Fish in cover and in deeper waters.


Rising...Clearing or improving...Fish tend to become slightly more active
Fish with brighter lures and near cover. Also fish at intermediate and deeper depths.


Normal and stable...Fair..Normal fishing
Experiment with your favorite baits and lures.


Falling...Degrading..Most active fishing..Speed up lures. Surface and shallow running lures may work well.



Slightly lower..Usually cloudy..Many fish will head away from cover and seek shallower waters. Some fish will become more aggressive.Use shallow running lures at a moderate speed.


Low..Rainy and stormy...Fish will tend to become less active the longer this period remains...As the action subsides, try fishing at deeper depths.






It is important to note that after a long feeding period, the action will slow regardless of the following conditions. On the flip side, a long period of poor fishing conditions may be followed by a really good one.
It is also important to note, that the barometric pressure is just one of many factors that effect fish feeding habits. Other effects include water temperature, light, tidal forces, water clarity, the pH level, water levels, wind/surface disturbance, boat traffic, fishing pressure, and so on. Another good judging factor of fishing is the solunar effects which play a role in the tidal and illumination factors.

I think that most animals are affected by this, I dont leave the hose we the barrometer has bottmed out, the bass won't be moving neither will the deer, now weh it start to raise i have found that the fish tend to start moving and feeding, if it start to rise quickkly, hold on tight its gonna be on.

I tought this was a good read

Thats pretty much how it goes Chuck. I try and go jsut before a front comes in and during the first part of it coming in, as it provides the best fishing. What I was talking about in your other thread is that the pressure on the east coast was dropping early yesterday morning, and then bottomed out and began rising around 9-10 AM due to high pressure building in behind of the storm. The bite was shutoff until it stabled back out, most of my info only showed a .05 drop and rise in the pressure yeterday. I believe that the pressure plays more into a fish bite than the solunar tables, because they will bite when the pressure drops regardless of the moon, at least in my experiences.

Reading MBHutton's post ...I found a top notch weather site that shows the barometric pressure..because his copy and paste said most home guages are not that accurate..Here is the link..

just type in your city and save to your favorites..Check the pressure and then check it again and see if it's fallen ..stable or rising,...I hopr you guys can get this to work for your area..look around and you will find the barometer reading..
OK ..I found it..you can add your city in the bottom..The barameter thing is near the bottom on the left..It;s been rising God is good..

OK ..time for a test with out looking..[8D]

True or false..

1. A rise in the barometer means good fishin..
Example 29.05 ---- 30.07

2. A drop in the barometer usally means poor fishing..
Example 30.01- 29.25

3. Cold fronts bring a rise in the barometer..

Examle 28.07--29.98

4. Fish usually go deep during a rise in the barometer
Example..28.95--30.05

5. A steady barometer usually means good fishing.
29.79 --29.80

Honestly..I don't know the answers to these questions..I do plan to get the answers though and store them in my long term memory.
Can someone please get them all right..
Thanks,
C7

OK I'll be the first to test...someone smart please grade my paper....I'm simply learning..

1. A rise in the barometer means good fishin..
Example 29.05 ---- 30.07
OK a rise means heaviness...I choose false because a rise means cold front..
FALSE

2. A drop in the barometer usally means poor fishing..
Example 30.01- 29.25
I'd say False..a drop in the guage means warmer weather ..lighter air..
FALSE..

3. Cold fronts bring a rise in the barometer..

Examle 28.07--29.98
TRUE because it's heavier air resulting in pressure.
4. Fish usually go deep during a rise in the barometer
Example..28.95--30.05
TRUE I think..propaply go deep to get away from the pressure

5. A steady barometer usually means good fishing.
29.79 --29.80
TRUE..I remember this from reading the post.[8D]

Very good grasshopper , you pass [8D]

Thanks Brett..
I feel good now.. I learned something new..
