Charleston, South Carolina – Scorching temperatures in the Lowcountry will push into the low 90s through Saturday, with mostly sunny skies and minimal relief before a potential round of showers and storms arrives late Sunday.
According to the National Weather Service in Charleston, high temperatures are expected to range from 85 to 92 degrees Thursday, with similar conditions persisting Friday and Saturday. Overnight lows will hover in the upper 60s to low 70s, offering little overnight cooling. Rain chances increase Sunday afternoon as a disturbance moves through the Southeast.
Charleston, Mount Pleasant, Summerville, and much of coastal South Carolina will feel the heat, with inland areas like Walterboro and Moncks Corner potentially reaching the mid-90s. Beachgoers and outdoor workers should prepare for extended sun exposure and stay hydrated. Local emergency officials advise avoiding strenuous activity during peak afternoon heat.
This warm spell is part of a broader pattern bringing hotter-than-normal May temperatures to much of the Southeast. While Friday and Saturday remain dry, thunderstorms could disrupt travel or outdoor plans late Sunday.
High heat will likely persist into next week, with additional updates expected if storm chances increase or heat advisories become necessary.
