Frost dates for Saxtons River, VT, ZIP 05143

Zone 5b

Around 05/13 is the usual last spring frost, about 258 days away. The first fall frost typically arrives around 10/03, about 143 frost-free days later.

Zone 5b (-15 to -10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Saxtons River, not a forecast for this year.

What to do before the first frost

Zone 5b around Saxtons River 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 05/13 isn't a guarantee

05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/28 and you're betting against frost in roughly 9 years out of 10. 05/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
