Henderson, NV 89026 Frost Dates
Henderson, NV: when does the frost end?
The last spring frost here typically falls around 01/21, about 146 days from today. Fall's first freeze usually shows up around 12/17, roughly 328 days after the last spring frost.
Zone 9a (20 to 25°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 Henderson, not a forecast for this year.
Stretching the season past the first frost
With roughly 16 weeks until Henderson's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/21 isn't a guarantee
01/21 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/29 and only about 1 year in 10 sees frost after that.
