Frost dates for Benton, LA, ZIP 71151

Zone 8b

Around 02/28 is the usual last spring frost, about 184 days away. The first fall frost typically arrives around 11/24, about 268 frost-free days later.

Zone 8b (15 to 20°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Benton, not a forecast for this year.

What to do before the first frost

Zone 8b around Benton has about 13 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 02/28 isn't a guarantee

02/28 is the middle of 30 years of NOAA records, not a promise. Plant by 02/04 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
