Des Moines, NM 88419 Frost Dates

88419, near Des Moines, NM: the frost window

Zone 6b

Around 05/05 is the usual last spring frost, about 250 days away. Fall's first freeze usually shows up around 10/09, roughly 156 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Des Moines in Zone 6b (-5 to 0°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Stretching the season past the first frost

Des Moines's growing season runs out in roughly 6 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/05 isn't a guarantee

05/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/23 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/20 and only about 1 year in 10 sees frost after that.
