Avondale, AZ: when does the frost end?
The last spring frost here typically falls around 01/14, about 139 days from today. 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.
Why 01/14 isn't a guarantee
01/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/19 and only about 1 year in 10 sees frost after that.
