A Freeze Warning is active overnight into Wednesday morning (March 18, 2026) across the Lowcountry and coastal Georgia, with lows dipping to 28°F in spots like Charleston, Summerville, and inland Berkeley/Dorchester counties.
Peak Conditions
Coldest hours hit between 2-8 a.m., fostering widespread frost inland while coastal areas like Mount Pleasant see lighter patchy effects. This late-spring chill—10-15°F below normal—stems from a high-pressure system enabling radiational cooling post a stormy front.
Precautions
Cover or bring in sensitive plants and early crops to avoid kill-off; insulate/drip exposed pipes; shelter pets indoors. Temps rebound post-sunrise, but watch for repeat cold snaps.
