Ohio features four distinct climatic seasons. Like much of the rest of the nation and world, the state is experiencing a gradual warming trend. Since the start of the 20th century, the temperature in Ohio has increased by over 1.5%.
Ohio’s three major cities are Cleveland, Columbus and Cincinnati. The average daily high temperature in July in Cincinnati is 86 degrees Fahrenheit, compared to 84 degrees in Columbus and only 81 degrees in Cleveland. In January, the average drops to 40, 37 and 35 degrees, respectively. Cleveland is positioned near Lake Erie and subject to lake breezes, resulting in the area seeing colder air throughout the year.
