Blue Mountain, MS 38610 Frost Dates

When can you plant in Blue Mountain, MS?

Zone 8a

The last spring frost here typically falls around 04/03, about 218 days from today. The first fall frost typically arrives around 10/30, about 210 frost-free days later.

The USDA Plant Hardiness Zone Map puts Blue Mountain in Zone 8a (10 to 15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 9 weeks of growing season left in Blue Mountain before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/03 isn't a guarantee

04/03 is the middle of 30 years of NOAA records, not a promise. Plant by 03/15 and you're betting against frost in roughly 9 years out of 10. 04/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
