Beverly Hills, CA 91403 Frost Dates
Beverly Hills, CA: when does the frost end?
The last spring frost here typically falls around 12/31, about 125 days from today. Fall's first freeze usually shows up around 12/30, roughly 365 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Beverly Hills 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 18 weeks until Beverly Hills's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 12/31 isn't a guarantee
12/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/09 and only about 1 year in 10 sees frost after that.
