*** 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
Natural Dam Lake, like many small Texas reservoirs, experiences noticeable seasonal swings in surface water temperature. Typical winter surface temperatures often range from about 45–60°F (7–16°C), while spring warms to roughly 55–75°F (13–24°C) as air temperatures rise. In summer the lake commonly reaches its warmest conditions, with surface readings often between 75–90°F (24–32°C), and late summer can push the upper end higher during heat waves. Fall generally cools back to the mid 60s–mid 70s°F (18–24°C). Actual temperatures vary with recent weather, depth, shade, inflows and wind; deeper water can remain several degrees cooler and thermoclines can form in the warm months.
Swimming is generally allowed at Natural Dam Lake in areas with public access and where signage does not prohibit it, because the lake is used for recreation. However, access and rules can vary by property owner and managing agency, so visitors should check posted regulations. Safety and water-quality concerns sometimes restrict swimming—low water levels, submerged hazards, strong currents near inlets, or algal blooms may prompt temporary advisories—so it’s wise to confirm current conditions before entering the water. Lifeguards are typically not provided, so swimmers should exercise caution.
