Gallup, NM 87347 Frost Dates
Gallup, NM: when does the frost end?
Typically, the last spring freeze lands around 06/05, roughly 281 days out. Fall's first freeze usually shows up around 09/25, roughly 109 days after the last spring frost.
Zone 6a (-10 to -5°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 Gallup, not a forecast for this year.
Stretching the season past the first frost
With roughly 4 weeks until Gallup's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 06/05 isn't a guarantee
06/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/22 and only about 1 year in 10 sees frost after that.
