*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Holston River, winding through Tennessee and Virginia, is a picturesque river with a rich history and diverse recreational uses. Its water temperature varies with the seasons and is influenced by dam operations along its course. In the spring and early summer, the water tends to be cooler, ranging from 50°F to 65°F (10°C to 18°C), while in the late summer months, it warms to around 65°F–75°F (18°C–24°C), especially in calmer sections downstream of reservoirs. These warmer conditions make parts of the river inviting for water activities during the summer.
While swimming in the Holston River is possible in certain areas, it is not a widely popular activity due to variable water quality, strong currents in some sections, and the river's focus on other recreational uses. Calm stretches near parks or access points can provide safe spots for wading or cooling off, especially on warm days. The river is better known for boating, fishing, and kayaking, with many people enjoying its scenic beauty from the water or along its banks. For those seeking safer swimming options, nearby lakes or designated recreational areas are often preferred.
