Frost Dates for 39069 — Fayette, Mississippi

Half of springs at Natchez, MS see their last 32°F night by March 16; only one in ten is past it by February 25, and one in ten still has one after April 6. Planting tender crops after March 26 leaves a 30% risk of a frost on them, after April 1 20%, and after April 6 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 73% of the 96 Mississippi stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.

In fall the first 32°F night comes by November 9 in half of years, as early as October 27 one year in ten, and holds off past November 27 one year in ten.
