Lomita, CA: when does the frost end?

Zone 10b

The actual range around Lomita'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.
