Frost dates for Monroe, NY, ZIP 10950
Typically, the last spring freeze lands around 04/10, roughly 225 days out. The first fall frost typically arrives around 11/01, about 204 frost-free days later.
Monroe sits in USDA Zone 6b (-5 to 0°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
What to do before the first frost
Zone 6b around Monroe has about 9 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 04/10 isn't a guarantee
04/10 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 04/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
