Paragonah, UT 84760 Frost Dates
Paragonah, UT: when does the frost end?
Around 05/21 is the usual last spring frost, about 266 days away. Fall's first freeze usually shows up around 09/29, roughly 130 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 Paragonah, not a forecast for this year.
Stretching the season past the first frost
With roughly 5 weeks until Paragonah's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/21 isn't a guarantee
05/21 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/08 and only about 1 year in 10 sees frost after that.
