Best Barometric Pressure For Fishing Re-printed with permission from Shawn Ward There are all kinds of things that you must keep track of when you’re going fishing. From the type of bait you use, to the rod that works best for a given species of fish, the list of things you have to remember can feel overwhelming. However, knowing the best barometric pressure for fishing is something you absolutely cannot overlook. When you’re considering the best times of day to fish, barometric pressure is one of those daily and seasonal fluctuations that will play a huge role in how many fish you catch – if any. Here’s a quick guide to understanding barometric pressure as it relates to your fishing. What Is Barometric Pressure? Barometric pressure is also referred to as “atmospheric pressure.” It is simply the force that is created by the weight of the air... But wait – isn’t air weightless? To a certain extent, yes. However, the combination of water vapor, gas atoms, and an assortment of other particles all produce a light force on the surface of the earth. At the top of a mountain, you are going to have less air above you than if you were at sea level. Therefore, a location at altitude has a lower barometric pressure than one at sea level. While barometric pressure remains relatively consistent in a climate, many factors can influence fluctuations related to local weather patterns. These weather patterns create pressure ridges of air that impact the barometric pressure. Numerous factors can impact barometric pressure, but it is ultimately determined by the temperature and the movement of the atmosphere. These two factors can cause both high and low pressure. While high pressure usually creates weather conditions that are clear, dry, and calm, low pressure gives you those days that are undeniably miserable – cloudy, windy, and wet. As a general rule of thumb, air tends to travel from areas of high pressure to areas of low pressure, which can intensify the weather conditions I mentioned above.
