Cloverdale, CA: when does the frost end?

Zone 10a

Around 02/25 is the usual last spring frost, about 181 days away. Fall's first freeze usually shows up around 12/03, roughly 279 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 Cloverdale, not a forecast for this year.

Stretching the season past the first frost

With roughly 14 weeks until Cloverdale's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

02/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/02 and only about 1 year in 10 sees frost after that.
