Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
Bill Waller Lake in central Mississippi experiences typical southern reservoir temperature shifts through the year. In winter the surface often cools to roughly 45–55 °F (7–13 °C). Spring sees a steady rise as waters warm to about 55–70 °F (13–21 °C). Summer surface temperatures frequently range from roughly 75–90 °F (24–32 °C), with the warmest readings in shallow coves on hot afternoons. In autumn the lake usually cools back into the 60–75 °F (16–24 °C) band. These are seasonal surface ranges and actual temperatures can vary with weather, depth, and local conditions such as inflows or shading.
Swimming is commonly practiced at Bill Waller Lake because it is a public reservoir used for recreation, and many visitors swim from shore, docks, and boat-accessible spots. However, areas may lack lifeguard supervision and some zones (near boat ramps, spillways, or private property) can be unsafe or restricted. Water temperature affects comfort and safety—cold winter water raises hypothermia risk while very warm summer water can increase bacterial growth—so local advisories, posted rules, and awareness of boat traffic and underwater hazards should guide whether and where to swim.
