Bakersfield, CA 93301 Frost Dates

Frost dates for Bakersfield, CA, ZIP 93301

Zone 9b

Typically, the last spring freeze lands around 01/17, roughly 142 days out. The first fall frost typically arrives around 12/15, about 334 frost-free days later.

The USDA Plant Hardiness Zone Map puts Bakersfield 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

Zone 9b around Bakersfield has about 16 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 01/17 isn't a guarantee

01/17 is the middle of 30 years of NOAA records, not a promise. Plant by 02/18 and you're betting against frost in roughly 9 years out of 10. 12/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
