Globe, AZ 85550 Frost Dates

Globe, AZ: when does the frost end?

Zone 9a

Around 05/16 is the usual last spring frost, about 261 days away. Fall's first freeze usually shows up around 10/13, roughly 149 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Globe in Zone 9a (20 to 25°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 Globe's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Globe's last frost

05/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 06/02 and only about 1 year in 10 sees frost after that.

Globe against the rest of the dataset
