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
Judd Slough, like many small sloughs and backwater lakes in Tennessee, experiences noticeable seasonal shifts in surface water temperature. In colder months the surface often cools to roughly 40–55°F (4–13°C). Spring brings warming, with typical ranges from about 50–70°F (10–21°C) as daylight and runoff increase. Summer is when shallow slough waters can become quite warm, commonly around 70–85°F (21–29°C) and occasionally approaching 90°F (32°C) in shallow, stagnant pockets on hot days. In autumn temperatures usually decline again to roughly 55–70°F (13–21°C). Local factors such as depth, shading, inflow, and recent weather will cause variation from these general ranges.
Swimming opportunities at Judd Slough depend on access, land ownership, posted rules and current conditions rather than temperature alone. Where public access is available and signage does not prohibit entry, water in the mid-to-high summer range (around 70–85°F, 21–29°C) is generally comfortable for recreational swimming. Cooler spring and fall waters may feel brisk, and winter conditions are typically too cold for most swimmers. Regardless of temperature, swimmers should consider potential hazards—submerged debris, vegetation, currents, and water quality—so it is advisable to observe local guidance and restrictions before entering the water.
