Angels, CA 95229 Frost Dates

95229, near Angels, CA: the frost window

Zone 9a

The last spring frost here typically falls around 02/20, about 176 days from today. Fall's first freeze usually shows up around 12/11, roughly 290 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

Angels's growing season runs out in roughly 15 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 02/20 isn't a guarantee

02/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/07 and only about 1 year in 10 sees frost after that.
