How does barometric pressure affect bass fishing?
You know the feeling. It’s raining out and the change of air pressure has you moving slow and fighting fatigue. Well, humans aren’t alone in feeling this change in equilibrium. Barometric pressure is defined as the pressure of the atmosphere (you’ve probably heard the term “atmospheric pressure”). It’s clear now, right? Try thinking of it this way. When barometric pressure is high, air is sinking and pushing on the ground. That same air must eventually rise because it has nowhere else to go. When it rises, air cools down and moisture condenses. With that condensation, barometric pressure goes down. [source: Shutt] The exact effect barometric pressure has on bass, if any, is not altogether clear. While there is very little scientific information to be found on the topic, many fisherman swear barometric pressure plays a large
