Questa, NM: when does the frost end?
Around 05/31 is the usual last spring frost, about 276 days away. Fall's first freeze usually shows up around 09/28, roughly 118 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Questa 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
With roughly 4 weeks until Questa's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
The actual range around Questa's last frost
05/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/18 and only about 1 year in 10 sees frost after that.
