Elko, NV 89803 Frost Dates
Elko, NV: when does the frost end?
Around 05/29 is the usual last spring frost, about 274 days away. Fall's first freeze usually shows up around 09/18, roughly 111 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Elko in Zone 5b (-15 to -10°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 3 weeks until Elko's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/29 isn't a guarantee
05/29 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/16 and only about 1 year in 10 sees frost after that.
