The climate of Clinton County can be classified as humid continental. It is one of the coolest and wettest counties in southern Ohio, although differences between it and other southern Ohio counties are usually very slight. Clinton County averages 42 inches (1,100 mm) of precipitation per year, including 30 inches (760 mm) of snow (Note: 1 inch of snow does not equal one inch of precipitation). Average July high temperatures reach the mid and upper 80s F although temperatures above 90 F are common, while lows are typically in the 60s F.

Clinton County lies within the till plains physiographic region, and is somewhat flat or gently rolling. The northern two thirds of the county were covered with an ice sheet during the Wisconsinan Stage, while the southern third was covered by ice sheets during the much older Illinoian Stage. Because of such a history with ice, glacial features are readily found on the landscape, such as moraines and kames.
