Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
Medina Lake, a reservoir in the Texas Hill Country, experiences a wide range of water temperatures through the year. Winter surface temperatures commonly sit between about 45 and 60°F (7–16°C), while spring warms the lake into roughly 55 to 75°F (13–24°C). Peak summer conditions can push surface readings into the mid‑70s to upper‑80s °F (24–31°C), especially in shallower coves and on hot, calm days. In autumn the water typically cools back toward the 60–75°F (16–24°C) band. These figures can vary locally and with lake level; shallow areas heat and cool faster than deeper sections, and prolonged drought or heavy rains can change temperatures and circulation patterns.
Swimming in Medina Lake is generally allowed because the reservoir is used for recreational activities, but opportunities depend on access, local rules, and current conditions. Many public and private access points permit swimming, yet most sites lack lifeguards and facilities, so swimmers should be self‑reliant and cautious. Fluctuating water levels expose hazards such as submerged stumps, steep drop‑offs and uneven shorelines, and occasional water quality issues like algae blooms can lead to advisories. Before entering the water, check current local guidance, be aware of conditions, and choose sheltered, accessible spots for safer swimming.
