Charleston, South Carolina – A sharp cold snap is set to grip the Lowcountry by Friday morning, bringing the coldest temperatures of the week to Charleston and surrounding coastal communities and raising concerns for pets, plants, and exposed pipes.
According to the National Weather Service in Charleston, low temperatures early Friday are expected to fall into the low 20s across much of coastal South Carolina, with upper 20s likely along the beaches and across the Charleston Peninsula. Rural areas of southeast Georgia, away from the coast, could dip into the upper teens.
The cold follows the passage of a strong front late Thursday, allowing dry air and calm winds overnight to drive temperatures down quickly. Forecasters note a high probability that some inland and sheltered locations will briefly fall to or below 20 degrees before sunrise Friday.
These conditions pose a risk to sensitive vegetation and outdoor pets, particularly in areas unaccustomed to prolonged cold. Officials urge residents to bring pets indoors, protect cold-sensitive plants, and ensure space heaters are used safely and away from flammable materials. Exposed plumbing, especially in older homes and crawl spaces, should be wrapped or allowed to drip overnight.
While roads are expected to remain dry, the cold may still impact early-morning commuters and outdoor workers. Anyone heading out before sunrise is advised to dress in layers and limit prolonged exposure to the cold.
Temperatures will rebound slowly Friday afternoon but remain below seasonal averages, with highs struggling through the 40s. Another chilly night is possible heading into Saturday, though conditions are expected to gradually moderate later in the weekend.
No freeze warnings are currently posted, but forecasters caution that additional cold-related advisories may be issued as confidence increases. Residents across the Charleston metro area are encouraged to monitor updates closely as the coldest air settles in by the end of the week.
