The Cheyenne River, located in the central United States, flows through the states of Wyoming and South Dakota. The water temperature in the river can vary significantly depending on the season and location along its course. During the summer months, especially in July and August, the water temperature can reach a comfortable range for swimming, typically between 18°C (64°F) and 24°C (75°F). This makes the Cheyenne River a pleasant spot for those looking to cool off during the warmer months, particularly in the areas where the river is wider and the current is gentler.

While the Cheyenne River is not as well-known for recreational activities as some of the larger rivers in the U.S., it still offers ample opportunities for swimming, especially for locals and visitors who enjoy more tranquil settings. The river features scenic spots where people can wade into the water or take a relaxing swim. The current can vary depending on the area, with some sections being calm and ideal for leisurely swims, while others may be faster and better suited for kayaking or fishing rather than swimming.

In the colder months, particularly from late fall through early spring, the water temperature in the Cheyenne River drops significantly, making swimming less practical. The river can become quite cold, with temperatures often falling below 10°C (50°F). However, the river remains an important waterway for local wildlife and offers other outdoor activities like fishing, boating, and wildlife viewing throughout the year. While it may not be a top destination for year-round swimming, the Cheyenne River provides a peaceful and refreshing spot for a swim during the warmer months.
