Frost dates for Sacramento, CA, ZIP 95825
Around 01/12 is the usual last spring frost, about 137 days away. 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

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.
