California City, CA 93505 Frost Dates
When can you plant in California City, CA?
Around 03/15 is the usual last spring frost, about 199 days away. The first fall frost typically arrives around 11/17, about 241 frost-free days later.
The USDA Plant Hardiness Zone Map puts California City in Zone 8b (15 to 20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 12 weeks of growing season left in California City before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/15 isn't a guarantee
03/15 is the middle of 30 years of NOAA records, not a promise. Plant by 02/21 and you're betting against frost in roughly 9 years out of 10. 04/17 is the safer bet, historically only a 1-in-10 chance of frost that late.
