Summer Heat / Dog Days

Weather condition

In the dog days of summer, bass escape the heat by going deep to cooler, oxygenated water, burying in shade and grass, or feeding at night. The play is early mornings, offshore structure, matted grass and docks for shade, or a night trip — the deep clear lakes hold up best.

Why: Beat the heat: deep, early, shade, or night.

The dog days are the hottest stretch of summer, when surface temperatures peak, thermoclines set up, and daytime oxygen and comfort push bass deep or into shade.

How it affects the bite

Extreme heat drives bass off the shallows into cooler, shaded, or deeper water.

Bite impact
Mixed
Activity level
Slow

What the bass do: Fish go deep, shade up, or shift their feeding to low light and dark.

Where they move: Deep offshore structure, matted grass, shaded docks, or up at night.

How to fish it

Go-to techniques: Offshore / Ledge Fishing, Deep Cranking, Football Jig, Frog Fishing, Dock Fishing / Skipping, Night Fishing.

Best lures: Deep-Diving Crankbait, Football Jig, Hollow-Body Frog, Swimbait.

When & where it matters

Most in play: Summer.

Especially on: Lake Travis · Lake Austin · Lake Buchanan

Reading it on the water

  • 100-degree afternoons
  • Bath-water surface temps
  • A dead midday bank bite

If the shallows go dead by mid-morning, follow the bait and cooler water offshore — or come back after dark.

Bryan's reasoning

Why fish deep or at night in the heat? In the worst heat the shallow water is too warm and low on oxygen for the better fish, so they slide out to the deep, cooler, oxygen-rich zone or wait for night — that's why our summer night trips on Travis and Austin are so good.

From Bryan's logbook

Based on Bryan Cotter's on-the-water observations.

Repeatable pattern · corroborated
The deep, clear water keeps Travis fishing through the heat better than most lakes - as the sun climbs, the bigger fish just slide out to deeper structure.

Repeatable pattern · corroborated
In the summer the recreational traffic is heavy, so I run night trips - quiet, cool, and the big bass are on the prowl away from the daytime crowds.
