Henderson, NV 89119 Frost Dates
When can you plant in Henderson, NV?
Around 01/20 is the usual last spring frost, about 145 days away. The first fall frost typically arrives around 12/15, about 333 frost-free days later.
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.
What to do before the first frost
About 16 weeks of growing season left in Henderson before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 01/20 isn't a guarantee
01/20 is the middle of 30 years of NOAA records, not a promise. Plant by 02/14 and you're betting against frost in roughly 9 years out of 10. 12/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
