Eloy, AZ 85141 Frost Dates
Eloy, AZ: when does the frost end?
Typically, the last spring freeze lands around 02/24, roughly 180 days out. Fall's first freeze usually shows up around 11/28, roughly 273 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Eloy 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 13 weeks until Eloy's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
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.
