Dixon, WY: when does the frost end?

Zone 5b

Around 06/01 is the usual last spring frost, about 277 days away. Fall's first freeze usually shows up around 09/18, roughly 108 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Dixon 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 Dixon's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Dixon's last frost

06/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/15 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.
