Jacksonville, VT 01367 Frost Dates
Frost dates for Jacksonville, VT, ZIP 01367
Typically, the last spring freeze lands around 05/14, roughly 259 days out. The first fall frost typically arrives around 10/04, about 143 frost-free days later.
The USDA Plant Hardiness Zone Map puts Jacksonville in Zone 5b (-15 to -10°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 5b around Jacksonville has about 5 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 05/14 isn't a guarantee
05/14 is the middle of 30 years of NOAA records, not a promise. Plant by 04/30 and you're betting against frost in roughly 9 years out of 10. 05/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
