How Barometric Pressure Affects Bass Behavior


Barometric pressure relating to bass fishing is a topic often debated among anglers. There are many myths and theories surrounding this subject. If you want to maximize your fishing game, then it is important to pay close attention to the weather. Often overlooked, the weather has more to do with the behavior of bass than you might think. That being said, we've outlined some important factors to keep in mind. Try following these tips and see if they help you out next time you hit the lake.

So, how does barometric pressure affect bass Behavior? Well, I don’t think anyone completely knows. The reason is there are too many factors to consider. What is causing the bass to behave a certain way? Is it the barometric pressure, the light conditions, or actually wind speed? Likely it's a combination. It could even be part of their survival mode. It may be better to look at barometric pressure as a gauge to know when the bass will start feeding heavy. This will help us determine which presentation and lures to choose. Let me explain...
Low Barometric Pressure (a storm is coming prefrontal conditions)
Okay, so we know from experience that bass will feed when the barometer is falling and a storm is approaching.



They will especially feed heavy right before a storm hits. When bass are aggressively feeding its time to fish with lures that move faster and can cover a lot of water in a short period of time. Lures like spinnerbaits, regular crankbaitslipless crankbaitsjerkbaits, and vibrating jigs make great choices under these conditions. Keep an eye on the local weather radar map while out on the water to see where the storm is and how fast it is approaching.
***Caution: Be smart, and get off the water if the storm looks bad.

High Barometric Pressure (Post frontal conditions)
Post frontal conditions can make it tough, but not impossible to catch fish. The bass will now be holding close to cover or a drop-off. Rainy conditions can still be a good time to catch bass, but when the front passes, out come those bright bluebird skies that anglers dread.

Since the bass are tight to cover, a vertical, slower presentation like a jig, shaky head or drop-shot rig are good lure choices now. Be patient, during this time you may need to make multiple casts to the same piece of cover. This is also when you find out who the real fishermen are, as this is a much tougher bite.
The barometric pressure will be higher now, but we can’t always assume that this is the only factor making the bass hold tight to the cover, or why they seem to be harder to catch. Other factors like calmer wind and bright sun are also big factors that will make bass hold tight to cover.
One final thought to keep in mind is that the bass just fed heavily right before the storm, after eating such a big meal it would make sense why the bass would be reacting slower. Think about how you feel after a big Thanksgiving dinner?

If you're serious about catching more bass, knowing what stage the barometric pressure is at can help in your decision making before you get on the water and while you are fishing.
