Bass and water temperature in Texas: what each range means for where and how you fish

A bass is cold-blooded, so the temperature of the water sets its pace: how much it eats, how deep it sits and how hard it will chase. That is why the same lake can fish completely differently in January and in July. Learn the ranges below and a single number from the water will tell you where to start looking and what to throw.

The ranges here are typical, drawn from the TPWD bass brochure and the guides listed at the bottom, read on the dates shown. Bass in a clear canyon lake and bass in a muddy South Texas tank do not follow the same calendar, and the numbers overlap in spring and fall. Use them as a starting point, not a rule.

The six ranges

• Winter, up to about 47°F. Bass are sluggish and hold deep in stable water, often near main-lake structure close to a channel. They eat less often but will take a bigger meal, so slow baits with long pauses, such as a jig with a bulky trailer, a stick bait or a jigging spoon, are the usual starting point.
• Pre-spawn, about 48 to 59°F and rising. Fish begin to leave their winter holes for the spawning flats and stage on the first drops along the way, often around 8 to 15 feet. Suspending jerkbaits, crankbaits and lipless crankbaits work, fished slow to moderate, and subtler in the lower 50s.
• Spawn, about 60 to 70°F. TPWD says Texas bass start to spawn near 60°F, anywhere from February into May depending on the region. The males sweep out nests in roughly 2 to 8 feet of water. Slow, repeated presentations in the bed zone are the usual approach.
• Active spring, about 65 to 79°F. This is the most active stretch for many anglers: fish go shallow early and late and back to the first structure change as the sun climbs. Moving baits, such as spinnerbaits, topwaters and lipless crankbaits, fit.
• Summer, about 80°F and up. Bass hold shallow at low light and move to deeper structure and shade in the heat of the day. Topwaters at dawn and dusk, then frogs over cover and slow bottom baits such as a Carolina rig, are common choices.
• Fall, about 55 to 64°F and falling. Bass follow shad into creek arms and onto nearby points. Lipless crankbaits, crankbaits, spinnerbaits and jerkbaits that match the bait are typical.

Notice that spring and fall overlap: a 58°F reading can be a pre-spawn fish in February or a fall fish in November. The month and whether the water is warming or cooling decide which, so look at the calendar and the last week of readings together.

Using a number you actually have

• Water, not air. Air temperature swings by the hour, while a lake warms and cools slowly. A warm afternoon after a cold week does not mean warm water.
• Measured versus estimated. A gauge reading is measured, and a model or a number from a different water is an estimate. TexCast shows a water temperature only where a gauge or a nearby gauge reports one, with the time it was read, and labels anything modeled.
• No gauge on your lake? Many waters do not have one. A boat's fish finder or a simple thermometer on a cord gives you a real number, and you can type it into the Lure Starting Point box on the Fish tab.
• Surface is not everywhere. A reading near the surface can be a few degrees off the water at the depth the fish are holding, especially on sunny afternoons.

Temperature and the fish you release

Warm water is hard on a bass you plan to let go. TPWD says release is stressful above 70°F and very stressful above 80°F, and advises avoiding catch-and-release for black basses in water deeper than 30 feet. In summer, land fish quickly, keep them wet and let them go right away. The release guide has the steps.
