Globe, AZ 85501 Frost Dates

85501, near Globe, AZ: the frost window

Zone 9a

Around 02/24 is the usual last spring frost, about 180 days away. Fall's first freeze usually shows up around 12/01, roughly 279 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

Globe's growing season runs out in roughly 14 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/24 isn't a guarantee

02/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/18 and only about 1 year in 10 sees frost after that.

Globe against the rest of the dataset
