Charleston, SC – Coastal hazards remain the top concern heading into the weekend as strong onshore winds keep dangerous rip currents and high surf in play. The National Weather Service in Charleston has extended a High Surf Advisory through 8 p.m. Saturday, warning of breakers up to 6 feet and life-threatening currents along area beaches.
According to the NWS Charleston office, northeast winds will gust as high as 25 mph through Saturday, creating hazardous marine conditions and continued risks for swimmers. Officials urge beachgoers to avoid entering the surf, as rip currents could overwhelm even experienced swimmers. Rough seas may also impact small craft in Charleston Harbor and offshore waters.
Saturday will bring partly sunny skies with highs in the upper 70s, but the pattern turns more unsettled late in the weekend. According to forecasters, scattered thunderstorms are expected to develop Sunday, particularly after daybreak, with locally heavy rain possible. The chance for showers and storms continues into Monday, raising concerns about wet roads, slower commutes, and potential disruptions to outdoor events.
The gusty winds and rough seas also pose a challenge for mariners, with NWS Charleston cautioning of hazardous boating conditions through at least Sunday morning. Travelers using I-26 and coastal routes should anticipate sudden downpours during storms. Residents are urged to secure loose outdoor items and remain alert for rip current alerts if heading to area beaches.
