Henderson, NV 89179 Frost Dates
Frost dates for Henderson, NV, ZIP 89179
Typically, the last spring freeze lands around 02/04, roughly 160 days out. The first fall frost typically arrives around 12/05, about 302 frost-free days later.
The USDA Plant Hardiness Zone Map puts Henderson in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
Zone 9a around Henderson has about 14 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 02/04 isn't a guarantee
02/04 is the middle of 30 years of NOAA records, not a promise. Plant by 01/10 and you're betting against frost in roughly 9 years out of 10. 02/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
