Indio, CA 92203 Frost Dates
Indio, CA: when does the frost end?
Typically, the last spring freeze lands around 12/31, roughly 125 days out. Fall's first freeze usually shows up around 12/27, roughly 365 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Indio in Zone 10a (30 to 35°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 17 weeks until Indio'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
12/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/10 and only about 1 year in 10 sees frost after that.
