What to do in Long Beach now
Long Beach is in warm-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Long Beach Daugherty Ap; each status uses this year's soil estimates.
Cool-season: tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue
- Crabgrass pre-emergent No clear spring window Typical: Soil rarely drops below 55°FSoil here stays warm enough for crabgrass to sprout in most months. Extension calendars in frost-free areas usually time a late-winter pre-emergent application by date rather than by soil temperature.
- Seed or overseed Seed now · about 45 days left Typical: Oct 30 – Dec 184-inch soil is 68°, inside the 55–70°F range where tall fescue and bluegrass sprout fastest. The window typically closes around Dec 18.
- 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 No clear spring window Typical: Soil rarely drops below 55°FSoil here stays warm enough for crabgrass to sprout in most months. Extension calendars in frost-free areas usually time a late-winter pre-emergent application by date rather than by soil temperature.
- Seed or sod Wait for late spring Typical: Apr 17 – Oct 30Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Apr 17.
- Fall pre-emergent (Poa annua) Germinating since Nov 1 Typical: By Oct 194-inch soil fell below 70°F on Nov 1, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Oct 19 next year.
- Dormancy and last feeding Expected about Dec 18 Typical: Around Dec 18Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 18. Make the last nitrogen feeding at least a month before that.

Which grass grows in Long Beach
With mild winters (January averages 57°F), most Long Beach 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 Long Beach
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.

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.

Long Beach questions
What is the soil temperature in Long Beach today? Our estimate for Nov 3 is 66°F at 2 inches and 68°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 Long Beach? Soil here rarely cools below 55°F, so there is no clean spring window; frost-free areas usually apply in late winter by calendar date.
When can I seed bermudagrass in Long Beach? 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 Apr 17.
Is it too late to fertilize in Long Beach? Expected about Dec 18. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 18. Make the last nitrogen feeding at least a month before that.
When is the last frost in Long Beach? The last 32°F night of spring has typically come around Jan 15, and as late as Jan 15 in 1 year in 10. The first fall freeze typically arrives around .
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.
