What to do in Waco now
Waco is in warm-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Waco Regional Ap; each status uses this year's soil estimates.
Cool-season: tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue
- Crabgrass pre-emergent Closed Feb 15 Typical: Feb 4 – Mar 22-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 4 – Mar 2, 2027.
- Seed or overseed Seed now · about 29 days left Typical: Oct 24 – Dec 24-inch soil is 71°, inside the 55–70°F range where tall fescue and bluegrass sprout fastest. The window typically closes around Dec 2.
- Late-fall feeding Soil rarely cools to 40°F Typical: Through winterRoots stay active through most winters here. Feed on the fall schedule your extension office gives for your grass, and avoid feeding a lawn that is dormant from drought.
Warm-season: bermudagrass, zoysia, St. Augustine, centipede, bahia
- Crabgrass pre-emergent Closed Feb 15 Typical: Feb 4 – Mar 22-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 4 – Mar 2, 2027.
- Seed or sod Wait for late spring Typical: Mar 26 – Oct 24Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Mar 26.
- Fall pre-emergent (Poa annua) Germinating since Oct 21 Typical: By Oct 224-inch soil fell below 70°F on Oct 21, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Oct 22 next year.
- Dormancy and last feeding Expected about Dec 2 Typical: Around Dec 2Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 2. Make the last nitrogen feeding at least a month before that.

Typical lawn dates in Waco
Each date is when the soil estimate (or the air, for freezes) crossed the threshold, year by year since 2005. “Early” and “late” are the 10th and 90th percentile years, so 8 years in 10 fall between them.

Checked against a real sensor
Measured nearby: 69°F at 2 inches on Nov 3, at the USDA SCAN site “Riesel”, 19 miles away.
Our estimate for Waco on Nov 3 is 70°F; the sensor read 71°F at 4 inches against our 71°F. Sensor sites sit in open, unwatered ground outside town, so they often run a few degrees apart from city lawns; use them as a check on the trend.
There is no soil sensor in most cities, so we estimate it. Shallow soil follows air temperature with a lag of a few days, and runs a little warmer than the air in fall. We fitted that relationship to 190 USDA soil-sensor stations; on years held out of the fit, the estimate was off by 3.3°F on an average day, and it put the spring 55°F date within a median of 3 days.

Waco questions
What is the soil temperature in Waco today? Our estimate for Nov 3 is 70°F at 2 inches and 71°F at 4 inches, as a daily average. Early-morning soil runs a few degrees cooler than that, and afternoon soil warmer.
When should I put down crabgrass pre-emergent in Waco? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 4 to Mar 2 in Waco. For 2026 the window closed on Feb 15.
When can I seed bermudagrass in Waco? Wait for late spring. Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Mar 26.
Is it too late to fertilize in Waco? Expected about Dec 2. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 2. Make the last nitrogen feeding at least a month before that.
When is the last frost in Waco? The last 32°F night of spring has typically come around Mar 14, and as late as Apr 7 in 1 year in 10. The first fall freeze typically arrives around Nov 16.
Why 2 inches and 4 inches? Crabgrass and most weed seeds sprout in the top inch or two, so pre-emergent timing follows 2-inch soil. Grass seed and roots respond to the slightly steadier soil at about 4 inches.
How accurate is this? It is a model, not a probe in your yard. Expect about 3–4°F of difference on a given day; shade, slope, mulch and irrigation all move real soil. The dates and trends are more reliable than any single day.
