Frost Dates for 39567 — Pascagoula, Mississippi

Half of springs at Pascagoula 3 NE, MS see their last 32°F night by March 8; only one in ten is past it by February 15, and one in ten still has one after March 31. Planting tender crops after March 18 leaves a 30% risk of a frost on them, after March 24 20%, and after March 31 10%. The 23 days between the even-odds date and the one-in-ten date is wider than at 92% of the 96 Mississippi stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
