93067, near Carpinteria, CA: the frost window

Zone 10b

Around 01/13 is the usual last spring frost, about 138 days away. Fall's first freeze usually shows up around 01/06, roughly 365 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Carpinteria in Zone 10b (35 to 40°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

Why 01/13 isn't a guarantee

01/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/24 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/12 and only about 1 year in 10 sees frost after that.
