Barometric Pressure and Fishing



Atmospheric Pressure Affects Fishing!


Some anglers swear by barometric pressure readings — to foretell changes in the weather.  Simply stated, a falling barometric pressure tells us that there is going to be a major change in the weather — a rain storm, perhaps.

When the barometric pressure is rising, or holding steady, weather conditions will be pleasant.

What Anglers Know

Old time fishermen know that  (generally) fish behavior is affected by barometric pressure.  For example:  Fishing isn’t particularly good while the barometric pressure is falling (This signifies a major weather change).

Anglers like rising barometric pressure because the best fishing occurs during these readings.  Fish seem to be more active during periods of slowly rising barometric pressure.

Another school of though with anglers centers around the steady atmospheric pressure score.  This group doesn’t care if the pressure is falling or rising — just so it remains steady!

Anglers as Weather Forecasters

Does this mean that all fishing enthusiasts should get a degree in meteorology? Of course not. Barometric pressure is only one part of the ‘weather picture.’

We cannot control or manufacture the weather.  Barometric pressure readings, generally, can help us determine whether it is worth our while to hang out our “Gone Fishin'” sign.

Other Weather Conditions

I always thought my grandfather was nuts when he wanted to go fishing while it was raining*.  Marine biologists have proved him right!

Rain and wind knock insects into the water.  Fish that eat insects take advantage of this free food by being more active — just under the water’s surface!

During this time, fish cannot see you as well  — rain droplets break up the water’s surface!

The Hot and Cold of Fishing

Another great time for fishing is just before a cold front blows into an area.  You and the fish will enjoy a cold front that breaks up hot, humid weather.

During the “lazy days of summer,” it takes more to tempt a fish from his cool spot.  This is the time to use a larger bait, lure, whatever.

It is also important to slow down your reeling in of the bait (on your line).  Slow-and-easy is better than jerky-and-fast.  Fish are sluggish in warmer water (in hot, humid conditions).


* I’m not referring to a storm with lightening or thunder. Fishing during a serious storm is foolhardy because lightening can strike you, your boat, your rod, etc. I’m sure you get the picture.
