*** 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
Lake Marble Falls, part of the Highland Lakes chain in central Texas, experiences a wide range of water temperatures through the year. In winter months surface temperatures often sit between about 45 and 60°F (7–16°C), while spring typically warms the lake to roughly 60–75°F (16–24°C). Summer brings the warmest conditions, with surface readings commonly in the 75–90°F range (24–32°C) and occasional spikes above that on hot spells. By autumn the water cools back toward springlike values, generally running about 60–75°F (16–24°C). Deeper water and areas shaded by boat wakes or inflows can be several degrees cooler than surface measurements.
Swimming in Lake Marble Falls is a common recreational activity and is permitted in many public access areas and parks along the shoreline, but it is regulated by local authorities and subject to safety and water-quality considerations. There are no widespread lifeguard services, and swimmers should avoid currents and boat traffic, particularly near dams and boat ramps. Periodic advisories for bacterial contamination or algal blooms can close or discourage swimming, so checking recent conditions before entering the water is advisable. Overall, summer offers the most comfortable temperatures for swimming, whereas winter and early spring waters can feel uncomfortably cold.
