Frost Dates for 89052 — Henderson, Nevada

Half of springs at Las Vegas WFO, NV see their last 32°F night by February 4; only one in ten is past it by January 10, and one in ten still has one after February 27. Planting tender crops after February 14 leaves a 30% risk of a frost on them, after February 21 20%, and after February 27 10%. The 23 days between the even-odds date and the one-in-ten date is wider than at 58% of the 38 Nevada stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.

In fall the first 32°F night comes by December 5 in half of years, as early as November 19 one year in ten, and holds off past December 23 one year in ten.
