Salinas, CA 93905 Frost Dates
Salinas, CA: when does the frost end?
Around 01/29 is the usual last spring frost, about 154 days away. Fall's first freeze usually shows up around 12/10, roughly 325 days after the last spring frost.
Zone 9b (25 to 30°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 Salinas, not a forecast for this year.
Stretching the season past the first frost
With roughly 15 weeks until Salinas's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/29 isn't a guarantee
01/29 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/18 and only about 1 year in 10 sees frost after that.
