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.

*** 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 Kirby, like many small Texas reservoirs, experiences pronounced seasonal shifts in surface water temperature. In winter months the lake often cools to roughly 45–60°F (7–16°C) depending on air mass passage and wind; spring brings a steady rise into the mid 50s to mid 70s °F (13–24°C) as sunlight and runoff warm the shallows. Summer surface temperatures commonly reach about 75–90°F (24–32°C) and can spike higher in shallow coves on hot, calm days, while autumn cooling generally returns waters to the 60–75°F (16–24°C) band as air temperatures decline. Deeper parts of the reservoir remain cooler year-round, and short-term weather patterns or inflows can shift surface readings by several degrees.
Swimming at Lake Kirby is permitted only where access and local rules allow, and conditions vary by shoreline ownership and management. Some stretches may be open for informal swimming, but other areas are private, posted, or unsuitable due to steep banks, submerged hazards, boat traffic, or variable water quality. There are often no lifeguards, so swimmers should heed posted advisories, use life jackets for open-water swimming, and avoid algae blooms or recent heavy runoff. For safety and legal use it’s best to confirm current local regulations and water-quality notices before entering the water.
