Lomita, CA 91618 Frost Dates
Lomita, CA: when does the frost end?
The last spring frost here typically falls around 01/09, about 134 days from today. 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 Lomita 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 19 weeks until Lomita's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/09 isn't a guarantee
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.
