The Ohio River, which flows through several states including Pennsylvania, Ohio, West Virginia, Kentucky, and Indiana, is one of the largest rivers in the United States. The water temperature in the Ohio River varies seasonally, with colder temperatures in the winter and warmer waters during the summer months. In winter, the temperature can drop significantly, often ranging between 30°F and 40°F (about 1°C to 4°C), making swimming unfeasible and dangerous due to the cold and strong currents. However, during the summer months, especially in late June through August, the water temperature typically rises to more comfortable levels for swimming, ranging from 70°F to 80°F (21°C to 27°C).

Swimming in the Ohio River is possible, but it comes with some precautions due to its strong currents and water quality. Certain sections of the river, particularly in more urban areas, may have higher pollution levels, which can make swimming less desirable. Still, there are spots where people venture into the water, particularly in areas where the river widens and the current slows down, such as in secluded coves or near certain riverfront parks. However, swimming in the Ohio River is generally more common among people who are familiar with the conditions and aware of potential safety hazards, including the presence of watercraft and the strength of the current.

In general, the Ohio River is more popular for recreational activities such as fishing, boating, and kayaking rather than swimming. Many people enjoy the river's scenery and use it for leisurely river cruises or water sports. Those interested in swimming should carefully research safe areas and monitor the weather and river conditions before deciding to enter the water, as the river's strong current can make swimming challenging, even in warmer temperatures.
