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.

*** 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
Clearwater Lake in southeastern Missouri experiences a broad seasonal swing in surface water temperatures. In winter the surface often falls into the mid-30s to mid-40s °F (about 2–7 °C). Spring brings steady warming with typical surface readings from the mid-40s to mid-60s °F (roughly 7–18 °C). Summer is when the lake is warmest, with surface temperatures commonly in the 70s to low 80s °F (about 21–28 °C) and occasionally reaching the mid-80s (around 29–30 °C) in shallow, sunlit coves. As autumn advances the water cools back into the 50s and lower 60s °F (approximately 10–17 °C). Deeper parts of the reservoir remain notably cooler year-round, and thermal stratification can produce sharp temperature gradients below the surface.
Swimming at Clearwater Lake is generally possible, but it is typically done at one’s own risk rather than under lifeguard supervision. The lake is used primarily for boating and fishing, and some shorelines, boat ramps, and marinas may be posted with restrictions; swimming near dams, busy boat channels, or launch areas is discouraged for safety reasons. Visitors should check local signage and follow seasonal advisories, be aware of sudden drop-offs and boat traffic, and exercise caution when entering colder or deeper water.
