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
The South Fork Rivanna Reservoir, which serves as part of the municipal water supply near Charlottesville, experiences typical mid-Atlantic seasonal water temperatures that vary with depth, weather and inflow. In winter surface temperatures commonly hover near freezing to the mid‑40s °F (about 0–7 °C). Spring sees a steady rise, with surface readings often in the mid‑40s to mid‑60s °F (roughly 7–18 °C) as air temperatures warm. Summer surface temperatures are usually the warmest, frequently ranging from the high 60s to low 80s °F (about 20–28 °C) in calm, shallow areas, while deeper zones remain noticeably cooler. In autumn the surface tends to cool back into the 50s and 60s °F (around 10–20 °C) as fall weather sets in.
Because the South Fork Rivanna Reservoir is managed primarily as a source of drinking water, swimming is generally not permitted; the restriction helps protect water quality and public health and reduces risks associated with unsupervised open‑water bathing. Recreational use tends to be limited and regulated, so anglers and boaters should follow posted rules and local authority guidance rather than assume casual swimming is allowed.
