Barometric Pressure and Bass

One of the most persistent myths in fishing is that barometric pressure controls the activity of bass and other gamefish. Although many researchers have tried, scientific studies have been unable to demonstrate that such a relationship exists. Every scientific report we’ve seen, in which barometric pressure was studied, reached a similar conclusion: no direct relationship is evident.

This consistency results mainly because no way has been found to isolate barometric pressure influences from simultaneous weather phenomena. We need observations of fish behavior when air pressure changes are the only variable. But significant barometric changes are rare without accompanying changes in wind, temperature, and sky conditions.
