Sacramento, CA 95816 Frost Dates

When can you plant in Sacramento, CA?

Zone 9b

The last spring frost here typically falls around 01/12, about 137 days from today. The first fall frost typically arrives around 12/16, about 341 frost-free days later.

The USDA Plant Hardiness Zone Map puts Sacramento in Zone 9b (25 to 30°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 16 weeks of growing season left in Sacramento before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 01/12 isn't a guarantee

01/12 is the middle of 30 years of NOAA records, not a promise. Plant by 02/08 and you're betting against frost in roughly 9 years out of 10. 12/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
