The Tanana River, flowing through central Alaska, is a major tributary of the Yukon River. Due to its northern location, the water temperature in the Tanana River tends to be quite cold year-round. In the summer months, the water temperature typically hovers around 50–60°F (10–16°C), which can feel refreshing but also chilly for prolonged swimming. During the winter, temperatures drop further, and the river may freeze over in many areas, making swimming entirely impractical.

Swimming in the Tanana River is not commonly recommended due to its cold temperatures, swift currents, and potential ice hazards in the colder months. However, some adventurous swimmers do take advantage of the river's warmer temperatures during the brief summer season, particularly in the slower-moving sections. These areas, often near tributaries or more sheltered spots, may provide an opportunity for a quick dip or wading. Despite these possibilities, the Tanana River is more popular for activities such as fishing, boating, and kayaking. Due to the cold water, swimmers should always exercise caution and be aware of the river's conditions before entering.
