Angels, CA 95249 Frost Dates
Angels, CA: when does the frost end?
Typically, the last spring freeze lands around 01/22, roughly 147 days out. Fall's first freeze usually shows up around 12/17, roughly 332 days after the last spring frost.
Zone 9a (20 to 25°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 Angels, not a forecast for this year.
Stretching the season past the first frost
With roughly 16 weeks until Angels's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/22 isn't a guarantee
01/22 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/23 and only about 1 year in 10 sees frost after that.
