Grants, NM 87051 Frost Dates
Grants, NM: when does the frost end?
The last spring frost here typically falls around 05/24, about 269 days from today. Fall's first freeze usually shows up around 10/01, roughly 129 days after the last spring frost.
Grants 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
With roughly 5 weeks until Grants's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/24 isn't a guarantee
05/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/07 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/09 and only about 1 year in 10 sees frost after that.
