The fish, meanwhile, have their own reaction to the weather. In some still waters, oxygen content may be uncomfortably low, making bass lethargic. There's probably less rain and wind, so the water around them is clearer than in other seasons. With light penetration at such high levels, bass can see much better and aren't as easily fooled by artificials. Being ambush predators, they also migrate to hard-to-reach places where they can use shade as cover, whether it's under boat docks, in the thickest parts of laydowns or even suspended in deep water.
