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.
