✅ 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
Old Hickory Lake, a reservoir on the Cumberland River in central Tennessee, experiences a wide range of surface temperatures through the year. In winter the water commonly falls into the mid-30s to upper-40s °F (about 2–9 °C), spring brings a gradual warming into the 50s and low 70s °F (10–22 °C) as runoff and air temperatures rise, and summer surface temperatures often reach the 70s to mid-80s °F (21–29 °C) on warm spells. During autumn the lake typically cools back into the mid-50s to low 70s °F (13–22 °C). These are general seasonal ranges; local weather, depth, and flow can make actual temperatures vary by location and day.
Swimming on Old Hickory Lake is possible in many spots because it is publicly accessible water, but it is not widely managed as a traditional swim beach. Many areas lack lifeguards and there are hazards such as boat traffic, variable currents, fluctuating water levels, submerged structures, and occasional water-quality advisories, so people swim at their own risk. Cooler shoulder-season temperatures increase the risk of cold-water shock and hypothermia, while summer temperatures are generally comfortable for swimming. Visitors should heed posted signs, follow any park or Corps of Engineers guidance, and use caution when entering the water.
