Frost risk by date in Spring Creek
Half of springs at Lamoille Yost, NV see their last 32°F night by June 6; only one in ten is past it by May 21, and one in ten still has one after June 23. Planting tender crops after June 13 leaves a 30% risk of a frost on them, after June 17 20%, and after June 23 10%. The 17 days between the even-odds date and the one-in-ten date is narrower than at 82% of the 38 Nevada stations behind this site's ZIP pages.
In fall the first 32°F night comes by September 16 in half of years, as early as August 31 one year in ten, and holds off past September 30 one year in ten. A hard freeze of 28°F follows 12 days later, around September 28; in spring the one-in-ten date for 28°F is June 11, 12 days before the 32°F one. The freeze-free season lasts 100 days in a typical year, shorter than at 97% of the 38 Nevada stations; it reaches 121 days one year in ten and falls short of 78 one year in ten.
