Barometric pressure is a measurement of the weight of the air in our atmosphere.

I believe it’s fair to say we’ve all watched the weatherman regularly talk about low and high pressure systems. These pressure systems are measurements of barometric pressure and can indicate an upcoming weather pattern. Watching the weatherman and deciphering these systems can increase your odds of success while out on the river.

Why?

Barometric pressure is a measurement of the weight of the air in our atmosphere. During a low pressure system, the weight of the air is decreasing and during a high pressure system the weight of the air is increasing. The weight of the air has a major effect in regards to fishing. A low pressure system means there is less weight or pressure pushing down on the water’s surface. This causes fish to be more active as it is easier for them to move. Conversely, a high pressure system can indicate warmer air and more pressure making it harder for fish to move.

I was fortunate to have experienced this pressure change earlier this summer as a low pressure system moved in. Forecasters predicted the system and the next morning the river exploded with activity. A significant change from the day before, birds and insects were swarming with great excitement. It was completely noticeable that something had changed and the fishing proved it.

Next time you hear the weatherman talk about low pressure, be sure to pay attention because your odds of success may be increasing.
