Frost dates for Moorhead, MS, ZIP 38761

Zone 8b

Around 03/08 is the usual last spring frost, about 192 days away. The first fall frost typically arrives around 11/20, about 255 frost-free days later.

The USDA Plant Hardiness Zone Map puts Moorhead in Zone 8b (15 to 20°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

Zone 8b around Moorhead has about 12 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

Why 03/08 isn't a guarantee

03/08 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 03/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
