*** 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
Beaverdam Reservoir in central Virginia experiences typical mid-Atlantic seasonal variations in surface water temperature. In winter the surface often ranges from about 34–45°F (1–7°C), with occasional near‑freezing patches during cold snaps. Spring brings a steady warming to roughly 45–68°F (7–20°C) as air temperatures rise and stratification begins to break down. Peak summer surface temperatures commonly sit between 70–85°F (21–29°C), though shallow bays can warm faster and exceed that briefly on hot, calm days. In autumn the water cools back toward the 50–70°F (10–21°C) window as cooler nights and stronger winds mix the water column and temperatures decline.
Swimming at Beaverdam Reservoir is generally not permitted because the impoundment functions as part of the regional water supply and is managed with public health and safety in mind. Restrictions are intended to protect drinking‑water quality, reduce contamination risks, and avoid hazards such as sudden depth changes, submerged structure, and the absence of lifeguard supervision. For those who want to swim, local parks or designated recreational lakes that allow bathing are safer options; visitors should consult official county or water‑authority rules before entering any reservoir water.
