Columbia, South Carolina – South Carolina residents will catch a break from oppressive humidity today as drier air spreads south, making outdoor conditions far more comfortable despite temperatures reaching near 90 degrees this afternoon.
According to the National Weather Service in Columbia, dew points—a key measure of air moisture—will fall into the mid-60s across most of central and eastern South Carolina by late afternoon. This shift means less muggy air for Columbia, Orangeburg, Sumter, and Myrtle Beach, where sticky conditions have dominated for much of July. The agency says dew points will hover around 64°F in Columbia, 68°F in Orangeburg, and 74°F along the coast in Myrtle Beach by 3 p.m. Wednesday.
With lower dew points, outdoor workers, commuters, and anyone exercising outside should notice less stickiness compared to recent days. Though temperatures remain seasonably hot, the reduced moisture will make it feel more comfortable and may help keep energy bills in check for those running air conditioners. The NWS recommends staying hydrated, limiting strenuous outdoor activities in peak afternoon heat, and keeping an eye on changing conditions—especially for those sensitive to air quality or heat.
This drier pattern is expected to persist through tonight, with another update likely by Thursday morning if conditions shift. Stay tuned to local advisories as weather patterns change later in the week.
