*** 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
Diascund Creek Reservoir, a managed drinking-water impoundment in eastern Virginia, exhibits typical seasonal surface-temperature swings for Mid-Atlantic lakes. In winter the surface often cools to roughly 34–45°F (1–7°C). Spring brings a steady warming, with surface readings commonly in the 45–65°F (7–18°C) band as air temperatures rise and stratification begins. Summer surface temperatures can reach the warmest levels, frequently in the 70–82°F (21–28°C) range at the warmest, shallow areas. During fall the reservoir generally cools back into the 50–68°F (10–20°C) window as mixing increases and daylight declines. These figures are approximate and vary with depth, weather patterns, and year-to-year conditions.
Swimming at Diascund Creek Reservoir is not permitted because the lake functions primarily as a municipal water supply and is managed to protect water quality and public health. Restrictions are intended to reduce contamination risk, limit shoreline impacts, and address safety concerns—cold, deep water and submerged hazards can pose drowning risks even when air temperatures are warm. Recreational use of the reservoir is therefore regulated, and visitors should follow local waterworks rules and posted signage rather than assume open swimming is allowed.
