Avondale, AZ: when does the frost end?

Zone 10a

Around 01/14 is the usual last spring frost, about 139 days away. Fall's first freeze usually shows up around 12/22, roughly 343 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Avondale in Zone 10a (30 to 35°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 17 weeks until Avondale'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
