Lincoln, CA: when does the frost end?
Around 02/11 is the usual last spring frost, about 167 days away. Fall's first freeze usually shows up around 11/30, roughly 289 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Lincoln in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here
02/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/12 and only about 1 year in 10 sees frost after that.
