Emigration Canyon, UT 84152 Frost Dates
Emigration Canyon, UT: when does the frost end?
Around 05/07 is the usual last spring frost, about 252 days away. Fall's first freeze usually shows up around 10/14, roughly 158 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Emigration Canyon in Zone 7b (5 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 7 weeks until Emigration Canyon's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/07 isn't a guarantee
05/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/27 and only about 1 year in 10 sees frost after that.
