*** 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.

Location & Local Information
Beech Lake’s water temperatures follow the seasonal pattern typical of small inland lakes in Tennessee. In winter the surface often cools to roughly 35–50°F (2–10°C), while spring sees a steady rise to around 50–65°F (10–18°C) as the lake mixes and warms. Peak summer temperatures commonly reach 70–85°F (21–29°C) in shallower areas and surface layers, with the warmest conditions from mid-June through August. During fall the water cools again, typically ranging from about 55–70°F (13–21°C) depending on air temperature and recent weather.
Swimming at Beech Lake is generally possible during the warmer months when surface temperatures are comfortable and local rules permit recreational use, but it depends on management, posted restrictions, and water quality. Many public lakes in Tennessee allow seasonal swimming because warm summer water supports recreational bathers, but authorities may close or limit access for safety reasons such as strong currents, submerged hazards, poor water clarity, contamination events, or harmful algal blooms. Cold water in spring and late fall increases the risk of hypothermia even when air temperatures seem mild. Visitors should check local signage and advisories, use designated swimming areas where available, and take standard water-safety precautions.
