Typically, the last spring freeze lands around 01/14, roughly 139 days out. The first fall frost typically arrives around 12/14, about 337 frost-free days later.
The USDA Plant Hardiness Zone Map puts Sanger 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 Sanger 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 01/14 isn't a guarantee
01/14 is the middle of 30 years of NOAA records, not a promise. Plant by 02/11 and you're betting against frost in roughly 9 years out of 10. 12/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
