*** 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
Ray Roberts Lake, north of the Dallas–Fort Worth area, experiences marked seasonal swings in surface water temperature. In winter months the lake often cools to roughly 40–55°F (4–13°C), while spring sees a steady rise into the mid‑50s to mid‑70s°F (13–24°C) as the weather warms. Summer surface temperatures commonly range from about 75–90°F (24–32°C), with the warmest readings in shallow coves and on calm afternoons; deeper water remains cooler. In autumn the lake typically cools again into the 60s–80s°F (16–27°C) before the winter decline. Actual temperatures vary with recent weather, depth, wind and inflow, so local readings can differ from these typical ranges.
Swimming at Ray Roberts is generally permitted in public access areas and at managed shoreline areas operated by the state park and Corps of Engineers, but conditions and rules vary by site. Most swim areas are unguarded, so swimmers should treat swimming as at‑your‑own‑risk and heed posted signs; certain boat ramps, marinas or restricted zones are not suitable or allowed for bathing due to boat traffic and safety regulations. Water‑quality advisories or algae blooms can occasionally prompt temporary closures, and cold winter temperatures can present hypothermia risk, so checking current park notices and exercising caution is recommended before entering the water.
