✅ 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.

*** 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
Somerville Lake, located in central Texas, experiences a wide range of surface water temperatures through the year. In winter months surface readings commonly sit around 45–60°F (7–16°C). Spring brings a steady warming with typical surface temperatures of roughly 55–75°F (13–24°C) as air temperatures rise. Summer is the warmest period, when surface waters often reach about 75–95°F (24–35°C), especially during extended heat spells; deeper water remains noticeably cooler. In autumn surface temperatures generally cool back into the 60–80°F (16–27°C) range. These values are approximate and change with recent weather, wind, inflows from tributaries, and reservoir release patterns, so local conditions can differ day to day and with depth.
Swimming in and around Somerville Lake is commonly permitted, particularly in park-designated swim areas, but it is subject to seasonal and site-specific rules and safety considerations. There are typically no lifeguards on duty, and shoreline swimmers share space with boating and fishing activities, so caution is advised. Water clarity, currents near inlets or the dam, underwater obstacles, and occasional algal or bacterial blooms can affect whether a site is suitable for swimming, which is why visitors are encouraged to follow posted notices and park guidance before entering the water.
