Frost risk by date in Amelia Court House

Half of springs at Amelia Courthouse, VA see their last 32°F night by April 7; only one in ten is past it by March 21, and one in ten still has one after April 21. Planting tender crops after April 13 leaves a 30% risk of a frost on them, after April 16 20%, and after April 21 10%. The 14 days between the even-odds date and the one-in-ten date is narrower than at 80% of the 128 Virginia stations behind this site's ZIP pages.

In fall the first 32°F night comes by November 2 in half of years, as early as October 20 one year in ten, and holds off past November 16 one year in ten. A hard freeze of 28°F follows 10 days later, around November 12; in spring the one-in-ten date for 28°F is April 9, 12 days before the 32°F one. The freeze-free season lasts 209 days in a typical year, longer than at 75% of the 128 Virginia stations; it reaches 231 days one year in ten and falls short of 189 one year in ten.
