Geography
According to the U.S. Census Bureau, the county has a total area of 412 square miles (1,070 km), of which 409 square miles (1,060 km) is land and 3.6 square miles (9.3 km) (0.9%) is water.
The entire county lies within the Little Miami River watershed, with the exception of extreme eastern areas, which are within the Scioto River watershed. 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.
The general elevation of the county is roughly 1,050 feet (320 m) above sea level, and there are few areas in the county that deviate from this by more than 200 feet (61 m).
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 (1.1 m) of precipitation per year, including 30 inches (0.76 m) of snow (Note: one 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. January high temperatures typically reach the low and mid 30s F, while lows generally bottom out in the 10s F, although lows in the single digits and even below 0 °F or −17.8 °C are common.
