Santa Barbara, CA: when does the frost end?

Zone 10b

The last spring frost here typically falls around 01/11, about 136 days from today. Fall's first freeze usually shows up around 12/16, roughly 342 days after the last spring frost.

Santa Barbara sits in USDA Zone 10b (35 to 40°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 16 weeks until Santa Barbara's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 01/11 isn't a guarantee

01/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/14 and only about 1 year in 10 sees frost after that.
