*** 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
Lake Mooney, a man-made reservoir in Virginia, experiences typical mid-Atlantic seasonal surface temperatures. In winter the water commonly sits around 34–45°F (1–7°C) near the surface, while spring brings a warming range roughly 45–68°F (7–20°C) as stratification begins. Peak summer surface temperatures often reach about 70–86°F (21–30°C) on warm days, with occasional localized warming in shallow coves, and autumn sees cooling back to roughly 50–70°F (10–21°C) as the lake mixes again. These figures are approximations for surface conditions; deeper water remains cooler year-round and exact temperatures vary with weather, depth and time of day.
Swimming at Lake Mooney is generally not permitted because the reservoir serves as a municipal water supply and is managed to protect water quality and public safety. Prohibiting direct human contact with the water reduces contamination risks, eases treatment needs, and lowers liability and rescue concerns where formal lifeguard supervision is absent. Visitors should check local signage and county regulations for the most current rules, as permitted activities and access points are determined by the managing authority to balance recreation with the primary function of supplying safe drinking water.
