*** 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
Welsh Reservoir in Texas experiences water temperatures that vary strongly with the seasons and with local weather. Surface temperatures in summer commonly sit between about 75 and 90°F (24–32°C), making the water pleasant for recreational bathing on warm days. In spring and fall the surface typically cools to roughly 60–75°F (16–24°C) as air temperatures moderate, while winter readings often fall into the 45–60°F range (7–16°C), especially in shallow areas or during cold snaps. Deeper water layers remain colder year-round, and wind, inflows, and recent rains can cause short-term fluctuations, so actual conditions at any given time may differ.
Swimming at Welsh Reservoir is generally allowed as part of its recreational use, but access can be limited by local regulations, water-quality advisories, or safety concerns such as low water levels, submerged hazards, strong currents, or high boat traffic. In summer the warmer surface temperatures make swimming comfortable for most people; in cooler months the much lower temperatures increase the risk of cold-water shock and hypothermia, so swimming is less advisable. Visitors should check current local notices and exercise standard water-safety precautions, since lifeguards are typically not present and conditions can change quickly.
