Beaufort, SC 29906 Frost Dates

When can you plant in Beaufort, SC?

Zone 9a

The last spring frost here typically falls around 02/28, about 184 days from today. The first fall frost typically arrives around 12/03, about 279 frost-free days later.

The USDA Plant Hardiness Zone Map puts Beaufort in Zone 9a (20 to 25°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

How much risk comes with planting early here

02/28 is the middle of 30 years of NOAA records, not a promise. Plant by 02/02 and you're betting against frost in roughly 9 years out of 10. 03/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
