*** 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.

The Osage River, located in central Missouri, is a significant tributary of the Missouri River. Its waters are largely influenced by the Bagnell Dam, which forms the Lake of the Ozarks, a popular recreational destination. The temperature of the river varies seasonally, with summer months bringing warmer waters, often ranging between 70°F and 80°F (21°C to 27°C), particularly in sections downstream of the dam. In winter, the river cools significantly, with surface temperatures dropping to the 30s or 40s (1°C to 9°C).
Swimming in the Osage River is possible, particularly in areas near the Lake of the Ozarks where the water is calmer and more accessible. However, strong currents in certain stretches and fluctuating water levels from dam operations can make swimming unsafe in some spots. Visitors should prioritize designated recreational zones or well-known swimming areas for a safer experience. Beyond swimming, the river is a favorite for fishing, boating, and kayaking, offering scenic views and abundant wildlife along its banks.
