Chandler, AZ: when does the frost end?

Zone 9b

Typically, the last spring freeze lands around 02/01, roughly 157 days out. Fall's first freeze usually shows up around 12/11, roughly 315 days after the last spring frost.

Chandler sits in USDA Zone 9b (25 to 30°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Stretching the season past the first frost

With roughly 15 weeks until Chandler's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 02/01 isn't a guarantee

02/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 02/27 and only about 1 year in 10 sees frost after that.
