Frost risk by date in Ramer

Half of springs at Selmer, TN see their last 32°F night by April 6; only one in ten is past it by March 19, and one in ten still has one after April 20. Planting tender crops after April 12 leaves a 30% risk of a frost on them, after April 16 20%, and after April 20 10%. The 14 days between the even-odds date and the one-in-ten date is narrower than at 95% of the 144 Tennessee stations behind this site's ZIP pages.

In fall the first 32°F night comes by October 30 in half of years, as early as October 18 one year in ten, and holds off past November 12 one year in ten. A hard freeze of 28°F follows 10 days later, around November 9; in spring the one-in-ten date for 28°F is April 11, 9 days before the 32°F one. The freeze-free season lasts 206 days in a typical year, longer than at 54% of the 144 Tennessee stations; it reaches 229 days one year in ten and falls short of 188 one year in ten. On average 74 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 11 days longer, to about April 17, and return around October 21. Severe cold of 16°F or below comes in 96% of winters, usually between December 26 and February 7.
