Maxwell, NM 87728 Frost Dates

87728, near Maxwell, NM: the frost window

Zone 6a

Around 05/17 is the usual last spring frost, about 262 days away. Fall's first freeze usually shows up around 10/01, roughly 135 days after the last spring frost.

Maxwell sits in USDA Zone 6a (-10 to -5°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.

Stretching the season past the first frost

Maxwell's growing season runs out in roughly 5 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/17 isn't a guarantee

05/17 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/31 and only about 1 year in 10 sees frost after that.
