89132, near Henderson, NV: the frost window
Typically, the last spring freeze lands around 02/04, roughly 160 days out. Fall's first freeze usually shows up around 12/05, roughly 302 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Henderson in Zone 9b (25 to 30°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
Henderson's growing season runs out in roughly 14 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 02/04 isn't a guarantee
02/04 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 02/27 and only about 1 year in 10 sees frost after that.
