Columbia, SC – A noticeably cooler stretch of October weather continues across South Carolina's Midlands on Sunday, Oct. 18, with afternoon temperatures struggling to climb beyond the 60s. Breezy conditions will add to the autumn feel, while Columbia could finish the day approximately 12 degrees below its seasonal average.
According to the National Weather Service in Columbia, temperatures will remain below normal Sunday following a chilly morning, with afternoon highs generally ranging from the lower to middle 60s across central South Carolina and nearby eastern Georgia.
The latest forecast, issued early Sunday morning, shows Columbia reaching approximately 64 degrees, compared with a normal October 18 high of 76 degrees.
How cold will South Carolina get Sunday?
Several Midlands communities are expected to experience similar temperatures.
Camden could reach 63 degrees, while Lancaster is forecast near 63 and Winnsboro around 62.
Newberry and Cheraw are expected to reach approximately 62 degrees, with Sumter and Manning near 64.
Farther south, Orangeburg could reach 65 degrees, while Aiken is forecast near 64.
Across the Savannah River in Georgia, Augusta could reach 66 degrees, approximately 12 degrees below its normal high of 78.
Will breezy conditions continue?
The National Weather Service expects another breezy day across the region, accompanying the cooler than normal temperatures.
Residents attending outdoor events, visiting parks or spending extended periods outside may want a light jacket, particularly during the morning and evening hours.
The supplied forecast does not indicate a specific wind advisory for the Columbia area.
When could warmer weather return?
Looking farther ahead, NOAA's Climate Prediction Center outlook for Oct. 25–31 favors above normal temperatures across much of South Carolina.
That suggests a warmer overall pattern could develop as Halloween approaches, although the outlook does not establish exact temperatures for Saturday, Oct. 31.
For now, Sunday will bring another taste of autumn across the Midlands, with temperatures running considerably below normal.
