Torrance, CA: when does the frost end?

Zone 10b

Typically, the last spring freeze lands around 01/09, roughly 134 days out. Fall's first freeze usually shows up around 01/05, roughly 365 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Torrance 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

With roughly 19 weeks until Torrance's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

The actual range around Torrance's last frost

01/09 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 12/04 and only about 1 year in 10 sees frost after that.
