Daly City, CA: when does the frost end?

Zone 10a

The last spring frost here typically falls around 12/30, about 124 days from today. Fall's first freeze usually shows up around 12/25, roughly 365 days after the last spring frost.

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 Daly City, not a forecast for this year.

Stretching the season past the first frost

With roughly 17 weeks until Daly City's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 12/30 isn't a guarantee

12/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/02 and only about 1 year in 10 sees frost after that.
