Frost risk by date in Estancia

Half of springs at Estancia 4N, NM see their last 32°F night by May 18; only one in ten is past it by May 5, and one in ten still has one after June 2. Planting tender crops after May 24 leaves a 30% risk of a frost on them, after May 29 20%, and after June 2 10%. The 15 days between the even-odds date and the one-in-ten date is narrower than at 46% of the 70 New Mexico stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 1 in half of years, as early as September 21 one year in ten, and holds off past October 15 one year in ten. A hard freeze of 28°F follows 9 days later, around October 10; in spring the one-in-ten date for 28°F is May 21, 12 days before the 32°F one. The freeze-free season lasts 135 days in a typical year, shorter than at 86% of the 70 New Mexico stations; it reaches 153 days one year in ten and falls short of 118 one year in ten. On average 183 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 14 days longer, to about June 1, and return around September 24. Severe cold of 16°F or below comes every winter, usually between November 7 and March 31.
