What to do in Indio now
Indio is in warm-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Desert Resorts 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: early Feb – Feb 152-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 1 – Feb 15, 2027.
- Seed or overseed Opens about Nov 6 Typical: Nov 6 – Dec 10Fall is the best time to seed. Start once 4-inch soil cools below 70°F, typically Nov 6, and finish while it is above 55°F, typically Dec 10.
- 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: early Feb – Feb 152-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 1 – Feb 15, 2027.
- Seed or sod Seed or sod now Typical: Mar 16 – Nov 64-inch soil is 70°. Seed planted later than late summer has little warm weather left to establish before dormancy.
- Fall pre-emergent (Poa annua) Apply within 2 days Typical: By Nov 5Annual bluegrass (Poa annua) starts sprouting when 4-inch soil falls below 70°F, typically Nov 5. A fall pre-emergent must be down before then. Skip it if you plan to overseed with ryegrass.
- Dormancy and last feeding Expected about Dec 10 Typical: Around Dec 10Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 10. Make the last nitrogen feeding at least a month before that.

Which grass grows in Indio
With mild winters (January averages 55°F), most Indio lawns are warm-season grasses such as bermudagrass, St. Augustine, zoysia and centipede. They grow through summer and slow or go dormant in winter.

Typical lawn dates in Indio
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.

| Pre-emergent window opens (2-inch soil 50°F) | early Feb | Feb 10 |

Where these numbers come from
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. Read the methodology.

Indio questions
What is the soil temperature in Indio today? Our estimate for Nov 3 is 68°F at 2 inches and 70°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 Indio? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been early Feb to Feb 15 in Indio. For 2026 the window closed on Feb 15.
When can I seed bermudagrass in Indio? Seed or sod now. 4-inch soil is 70°. Seed planted later than late summer has little warm weather left to establish before dormancy.
Is it too late to fertilize in Indio? Expected about Dec 10. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 10. Make the last nitrogen feeding at least a month before that.
When is the last frost in Indio? The last 32°F night of spring has typically come around Feb 12, and as late as Mar 4 in 1 year in 10. The first fall freeze typically arrives around Dec 5.
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.
