The USDA Plant Hardiness Zone Map puts Lomita in Zone 10b (35 to 40°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

Why 01/09 isn't a guarantee
01/09 is the middle of 30 years of NOAA records, not a promise. Plant by 02/24 and you're betting against frost in roughly 9 years out of 10. 12/04 is the safer bet, historically only a 1-in-10 chance of frost that late.
