Chowchilla, CA: when does the frost end?
Around 02/26 is the usual last spring frost, about 182 days away. Fall's first freeze usually shows up around 11/25, roughly 273 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Chowchilla in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 13 weeks until Chowchilla'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
02/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/01 and only about 1 year in 10 sees frost after that.
