Frost Dates in Virginia

At the middle station of the 119 in Virginia where a freeze comes every year, the last spring frost (50%) is April 13 and the first fall frost October 29, a freeze-free season of 198 days. The last frost is earliest at Norfolk (Norfolk NAS, VA, March 16) and latest at North Tazewell (Burkes Garden, VA, May 9), 54 days apart. The season runs from 150 days at North Tazewell to 255 at Norfolk.

91 of these stations were also in NOAA's previous normals, for 1981–2010. Between the two, the median station's freeze-free season grew 7 days longer, with the last spring frost 3 days earlier and the first fall frost 4 days later; the season lengthened at 76 stations and shortened at 12. The two periods share twenty years, so the change reflects mostly 2011–2020 against 1981–1990.
