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
Shearon Harris Reservoir, the cooling lake associated with the Shearon Harris power station in central North Carolina, experiences wide seasonal variation in surface temperatures. In winter months water commonly runs in the low 40s to mid-50s °F (about 4–13 °C), spring brings a steady rise into the 50s and lower 70s °F (10–22 °C), summer surface temperatures frequently reach the 70s to mid‑80s °F (21–29 °C) and can be locally warmer near plant discharge points, and autumn typically cools back into the mid‑50s to mid‑70s °F (13–24 °C). Because it functions as a cooling reservoir, temperatures can be uneven across the lake and may change quickly around outflow areas, producing warmer pockets even in cooler seasons.
Public swimming is generally not permitted or is heavily restricted at Shearon Harris Reservoir. The lake is part of utility operations, so safety, security and environmental considerations — including the presence of thermal discharges, variable currents, submerged infrastructure and regulated access — lead the operator and regulators to limit swimming. Recreational use that is allowed is typically managed (for example, controlled boating or fishing with permits), but anyone interested in entering the water should verify current rules with the managing authority because regulations and permitted activities can change.
