Milan, NM: when does the frost end?

Zone 6a

Around 05/29 is the usual last spring frost, about 274 days away. Fall's first freeze usually shows up around 09/26, roughly 118 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Milan in Zone 6a (-10 to -5°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

With roughly 4 weeks until Milan's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Milan's last frost

05/29 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/12 and only about 1 year in 10 sees frost after that.
