Many anglers believe that a bass cannot read differences in Air Pressure.
According to many studies, if a bass is holding in three-feet of water, a difference in water pressure caused by a difference in air pressure would be so low that neither man nor fish could detect it.
But, If that bass changes depth by three inches, the change in water pressure would be far greater than any change caused by a change in air pressure. And a bass changes depths by more than three-inches several times an hour, while it takes eight or more hours for the change in air pressure that is equal to a three-inch change in water depth.
There is an alternate theory. Moist air is lighter (weighs less) than dry air; and warm air is lighter than cold air. Therefore, warm moist air causes low air pressure readings, not the other way around.
Conversely: dry, colder air causes increases in air pressure, not the other way around.
When the atmosphere changes from sunny to cloudy,the air pressure drops and the fish react to the change in cloud cover,not to the change in air pressure. Similarly,a cold front is a mass of cold, dry air that pushes away any warmer, moister air in front of it. When a cold front approaches we see cloudy, rainy weather,which causes a drop in air pressure. Then,immediately behind the front there is cooler,clear,dry air. These conditions cause a rise in air pressure.
Differentials in air pressure behind the front cause a strong northerly wind.The bass react to changes in cloud cover and changes in wind, not to changes in air pressure.
When a cold front passes through, it has a major effect on bass fishing. Whether it is cause or effect, the bass seem to get lockjaw after a cold front passes through.
Bass instinctively hold close to cover when the sun is shining, and they scatter as the sky clouds over. When the sun is shining expect the bite to come when the lure is close to cover. On cloudy days the bite can occur anywhere. On sunny days constantly toss the lures at cover. On cloudy days fan cast large areas. On sunny days toss crankbaits or spinner baits at cover, but if this does not work, toss jigs-and-pigs or soft plastic at the cover.
On cloudy days work large areas rapidly with crankbaits or spinner baits, and sometimes throw soft plastic at cover.
With either sun or clouds, try throwing a lizard on a Carolina rig, but work the rig more rapidly on cloudy days than on sunny days.
And last but not least.....

ONE OF THE MOST IMPORTANT FEATURES
IS TO REMEMBER THAT FISH DO NOT HAVE HANDS So
IF YOU FEEL A BITE.....SET THE HOOK !!!!!
