Frost dates for Stockton, CA, ZIP 95207
Around 02/05 is the usual last spring frost, about 161 days away. The first fall frost typically arrives around 12/08, about 305 frost-free days later.
The USDA Plant Hardiness Zone Map puts Stockton 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 Stockton has about 15 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 02/05 isn't a guarantee
02/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/11 and you're betting against frost in roughly 9 years out of 10. 12/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
