Why Fish Stop Biting Midday
The short answer: bright sun and calm water push fish deeper, and in summer the warm surface holds less oxygen. What changes at midday, where the fish go, and how to keep catching them, following the Missouri Department of Conservation and the USGS.
The short answer: fish don’t stop eating at noon, they move. The Missouri Department of Conservation (MDC) says fish are generally in deeper water when the sun is bright and the wind is calm, and in shallower water in low light and choppy conditions; fish seem to prefer the low light of morning and evening to bright midday sun. Find where they went and slow down, and midday is still catchable.
What changes at midday
- Light. Bright sun and calm water send fish deeper (MDC).
- Heat and oxygen. In summer, MDC says heat sends fish deeper to find cooler water, though not to the bottom, where there is little oxygen. The USGS explains that cold water holds more dissolved oxygen than warm water, and that in summer the oxygen level in surface water is often lower.
- Disturbance. MDC notes that commotion on a dock, shore or boat can scare fish or stop them feeding.
Where the fish went
MDC’s guide to fish location points to the places to try:
- Deeper structure: drop-offs, points, ridges and sandbars, which often hold more fish than flat bottoms.
- Shade and cover: docks, overhanging trees, weeds, brush and logs shade fish and hide them.
- Edges: the edge of a weed line, the break between muddy and clear water, the edge of the main lake basin.
- Wind-blown banks: MDC says fish move shallower to feed when it’s windy, and that fishing is usually better where the wind blows into the shore.
How to catch them anyway
- Go deeper than the morning fish. Electronics help; our sonar reading guide covers finding fish on the screen.
- Fish the shade and the cover listed above, casting beyond the fish and working the bait into them (MDC).
- Slow down. A bait worked slowly near cover gives a fish holding in place an easy meal.
- Use cloud. MDC notes that cloud cover creates a twilight of its own and may encourage fish to bite.
And the plain truth from MDC: fish seem to prefer the low light of morning and evening. If you can only fish an hour, fish an edge of the day; the best fishing times tool combines time of day, weather and season for a quick read.
The bottom line
Midday doesn’t switch fish off. Bright light and calm water move them deeper and into cover, and summer heat pushes them toward cooler water. Follow them down, fish the shade and slow down.
