Sacramento, CA 95673 Frost Dates
Sacramento, CA: when does the frost end?
The last spring frost here typically falls around 02/22, about 178 days from today. Fall's first freeze usually shows up around 11/24, roughly 277 days after the last spring frost.
Sacramento 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 13 weeks until Sacramento's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/22 isn't a guarantee
02/22 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 04/01 and only about 1 year in 10 sees frost after that.
