Water Temperature
Water condition
Water temperature is the master variable in bass fishing. It sets the spawn timing, the fish's metabolism and aggressiveness, and where they live. Cold water means slow and deep; the pre-spawn 50s–60s means the year's best bite; the 70s are prime shallow feeding; and 85-plus pushes fish deep, early and to night.
Why: The master variable — it drives everything.

Water temperature is the measured warmth of the water, the primary driver of bass metabolism, spawning behavior, and seasonal location.
How it affects the bite
It controls metabolism, feeding rate, spawn timing and where bass position — everything keys off it.
- Bite impact
- Mixed
- Activity level
- Neutral
What the bass do: Cold = slow and deep; warming = moving up and feeding; hot = deep, shaded or nocturnal.
Where they move: From deep winter areas to shallow spawning flats to deep summer refuge, tracking temperature.
What the numbers mean
| Range | What it means |
|---|---|
| Below 48°F — winter | Slow metabolism; fish deep and lethargic. Finesse and jerkbaits, long pauses. |
| 48–58°F — pre-spawn staging | Fish stage on points and move up; reaction baits and jigs shine. |
| 58–68°F — spawn | Bass spawn on shallow flats; sight-fishing and the best big-fish window. |
| 68–78°F — post-spawn / prime | Aggressive shallow feeding; nearly every technique works. |
| 78–85°F — summer | Early and offshore; grass and shade midday. |
| Above 85°F — peak heat | Deep, shade, low-light and night; shallow water too warm midday. |
How to fish it
Go-to techniques: Jerkbait, Squarebill Cranking, Texas Rig, Offshore / Ledge Fishing, Walking Topwater.
Best lures: Jerkbait, Squarebill Crankbait, Senko / Stickbait, Deep-Diving Crankbait.
When & where it matters
Most in play: Spring, Summer, Fall, Winter.
Reading it on the water
- Your graph's surface temp reading
- Seasonal air trends
- Water color and clarity changes with temp
Check the surface temp first thing — it tells you how fast to fish, how shallow, and what stage the fish are in.
Bryan's reasoning
Why check water temp before anything else? The temperature tells me the whole story — where the fish are in their year, how aggressive they'll be, and how fast I should fish. I look at the graph's temp reading before I make my first cast and let it set the whole game plan.
From Bryan's logbook
Based on Bryan Cotter's on-the-water observations.
The number one thing I look for on Buchanan is rock - the largemouth love it, partly because it lets them tuck away from the striper, and the best rock holds the best fish. In cold water, when you think you're fishing slow enough, slow down more; that's how the giants come.
Because Fayette is a power-plant lake, the bass spawn early here - before the other lakes in the region - so it produces well even when it's still cold out. It's the best average-quality lake I know of in Texas.
