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 Swamp Reservoir in Virginia typically follows the seasonal temperature patterns of shallow, temperate reservoirs. Surface water in winter can hover near freezing up to the mid-40s °F (about 0 to 7 °C), while spring sees a gradual rise into the mid-40s to low 60s °F (7 to 17 °C). By summer the surface commonly warms into the upper 60s to upper 70s °F (20 to 26 °C), sometimes higher in very warm, shallow bays, and autumn brings cooling back down through the 50s to 60s °F (10 to 17 °C). Thermal stratification can produce cooler bottom temperatures in summer, and sudden weather shifts can change surface temperatures quickly, affecting comfort and safety for swimmers.
Swimming at Beaverdam Swamp Reservoir is generally restricted or discouraged, primarily because many reservoirs are managed for water supply, habitat protection and public safety rather than recreational swimming. Restrictions are intended to reduce contamination risks to potable water, limit disturbance to wildlife and submerged infrastructure, and prevent accidents related to cold shock, underwater hazards or sudden currents. In addition, issues like aquatic vegetation and occasional algal blooms can make wading or swimming unsafe. Anyone considering entering the water should check current local signage and management rules and follow guidance from the responsible agency.
