The USDA Plant Hardiness Zone Map puts Yuba City 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 Yuba City has about 14 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 02/14 isn't a guarantee
02/14 is the middle of 30 years of NOAA records, not a promise. Plant by 01/02 and you're betting against frost in roughly 9 years out of 10. 03/31 is the safer bet, historically only a 1-in-10 chance of frost that late.
