Also, many predatory fish will feed throughout the day in shallow water, even in hot summer weather. Falling pressure influences fish to become more active along shorelines, whereas rising pressure leads to a decrease in fish activity and poorer fishing. Wind action creates alternatives in the fish's environment. On a cool, windy summer day, the windward bank may present temperatures and oxygen levels more favorable to his disposition. Wind may also concentrate forage.
Wind direction does seem to affect fishing.
Weather that has a warming effect on water may also set off increased activity. It varies in depth and thickness, depending on the size and shape of a reservoir. Temperature and oxygen levels in this zone usually favor the comfort of most species. Avoid fishing below the thermocline in summer due to low oxygen levels. During early spring the northern portion of ponds and reservoirs tend to warm faster and will stimulate more activity than other areas.
