Sedona, AZ: when does the frost end?

Zone 8b

Around 04/14 is the usual last spring frost, about 229 days away. Fall's first freeze usually shows up around 11/05, roughly 204 days after the last spring frost.

Zone 8b (15 to 20°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Sedona, not a forecast for this year.

Stretching the season past the first frost

With roughly 10 weeks until Sedona's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 04/14 isn't a guarantee

04/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/04 and only about 1 year in 10 sees frost after that.
