*** 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
Lake McKellar, a shallow impoundment in western Tennessee, experiences typical seasonal surface temperatures for mid‑southern U.S. lakes. In winter (December–February) surface readings often range from about 40–55°F (4–13°C). Spring (March–May) sees a steady rise to roughly 55–70°F (13–21°C) as air temperatures warm. Peak summer (June–August) surface waters commonly warm to the mid‑70s to mid‑80s °F, about 24–29°C, occasionally higher during heat spells. In autumn (September–November) temperatures usually fall back into the 60–75°F (16–24°C) band as cooling progresses. Deeper or more shaded coves may stay cooler than open areas, and short‑term weather patterns, river inflows, and groundwater can also affect readings.
Swimming at Lake McKellar is not organized around maintained public beaches, so it is not widely promoted as a formal swim destination. Occasional informal wading or swimming does occur where public access permits, but there are often no lifeguards, shoreline amenities, or routine water‑quality monitoring specific to recreational swimming. Factors such as aquatic vegetation, boat traffic, variable clarity, and the potential for algal or bacterial advisories mean many local authorities and recreation guides encourage caution and checking current conditions before entering the water.
