In the end, most of the theories come to the same conclusion. When barometric pressure is at a high, bass fishing will be at a low, especially in shalloÂ­w waters, where changes in pressure are more easily felt. [source: Adams ] Some say that the bass swim bladder is sensitive to changes in air pressure. Â­When barometric pressure is high, the swim bladder feels increased pressure and the fish becomes slow and tired.
1 Falling or Low Barometric Pressure. 2  Deteriorating weather or some form of precipitation such as wet and/or windy conditions and thunder in hot weather are associated with falling barometric pressure. 3  As a storm approaches air pressure begins to fall and this can happen very quickly.verage Sea-Level pressure: 101.325 kPa /1013.25 mbar / 760 mmHg / 29.921 inHg. Pressures seldom increase or decrease 1 inch of mercury (3.386 kPa /33.86 mbar / 25 mmHg) above or below the 30 inch mark (101.591kPa / 1015.91 mbar / 762 mmHg) unless weather conditions are extreme.
