Stockton, CA 95204 Frost Dates
Stockton, CA: when does the frost end?
The last spring frost here typically falls around 02/05, about 161 days from today. Fall's first freeze usually shows up around 12/08, roughly 305 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 Stockton, not a forecast for this year.
Stretching the season past the first frost
With roughly 15 weeks until Stockton's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/05 isn't a guarantee
02/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/27 and only about 1 year in 10 sees frost after that.
