Columbia has a climate marked by sharp seasonal contrasts in temperature, falling between a humid continental and humid subtropical climate (KÃ¶ppen Dfa/Cfa, respectively), and is located in USDA Plant Hardiness Zone 6a.
While a bit far away for air service and other city amenities, Columbia does enjoy a good central location relative to Atlanta 200 miles west, Charleston and the coast 120 miles southeast, and the mountains northwest. Columbia is located at a river confluence. Surrounding terrain is rolling and slopes gently from north to south. The climate is humid subtropical. The Appalachian ridge 150 miles to the northwest frequently retards the approach of cold weather in the winter but offers little moderating effect on the summer heat.
