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
Houston County Lake in east Texas experiences a broad annual range of surface water temperatures typical of the region’s humid subtropical climate. In winter months the lake often cools to roughly 40–55°F (4–13°C). Spring brings a steady rise, generally in the 55–70°F (13–21°C) range, while summer surface temperatures commonly sit between about 70–85°F (21–29°C) and can occasionally climb toward the low 90s°F (around 32°C) during heat waves. In autumn the lake cools back into the 60–75°F (16–24°C) window as daytime air temperatures moderate. Actual temperatures vary with depth, weather patterns, and inflow conditions, so on any given day surface readings can differ from seasonal averages.
Swimming at Houston County Lake is generally permitted because the waterbody is used for public recreation, including fishing, boating, and occasional shoreline activities. There are often no staffed lifeguard services, so swimmers should exercise caution, be mindful of boat traffic, submerged vegetation and sudden depth changes, and obey posted rules. Water quality can change seasonally—heavy rains, runoff or algal blooms can prompt advisories or temporary closures—so checking local notices and using common-sense safety practices (life jackets for weak swimmers, avoiding swimming alone) is recommended before entering the water.
