Burbank, CA 91401 Frost Dates
When can you plant in Burbank, CA?
Around 12/31 is the usual last spring frost, about 125 days away. The first fall frost typically arrives around 12/30, about 365 frost-free days later.
Zone 10a (30 to 35°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Burbank, not a forecast for this year.
What to do before the first frost
About 18 weeks of growing season left in Burbank before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 12/31 isn't a guarantee
12/31 is the middle of 30 years of NOAA records, not a promise. Plant by 01/27 and you're betting against frost in roughly 9 years out of 10. 12/09 is the safer bet, historically only a 1-in-10 chance of frost that late.
