Henderson, NV 89111 Frost Dates

When can you plant in Henderson, NV?

Zone 9b

Around 01/21 is the usual last spring frost, about 146 days away. The first fall frost typically arrives around 12/17, about 328 frost-free days later.

Zone 9b (25 to 30°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.

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 01/21 isn't a guarantee

01/21 is the middle of 30 years of NOAA records, not a promise. Plant by 03/05 and you're betting against frost in roughly 9 years out of 10. 12/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
