Las Vegas, NV 89106 Frost Dates
Las Vegas, NV: when does the frost end?
The last spring frost here typically falls around 01/24, about 149 days from today. Fall's first freeze usually shows up around 12/10, roughly 323 days after the last spring frost.

Stretching the season past the first frost
With roughly 15 weeks until Las Vegas's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
01/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/27 and only about 1 year in 10 sees frost after that.
