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
Coleto Creek Reservoir, located in coastal Texas, typically follows seasonal patterns common to southeastern Texas impoundments. Surface temperatures in winter often fall into the mid-40s to mid-50s °F (7–13 °C), warming through spring into the mid-60s to mid-70s °F (18–24 °C). By summer, surface readings commonly reach the mid-70s to low 90s °F (24–33 °C), with the hottest late-summer afternoons producing the warmest surface pockets. Deeper water stays noticeably cooler than the surface, and localized warm zones can occur near plant discharge or shallow, wind-sheltered coves where solar heating is strongest. Nighttime cooling and inflows also create variability day to day.
Swimming is generally permitted in parts of the reservoir, particularly at park-designated access points, but it is not a lifeguarded or formally supervised beach in most areas. Recreational use is dominated by boating and fishing, so swimmers should avoid heavy boat lanes, steep drop-offs and any zones posted as restricted. The presence of power-plant discharge, changing water levels, submerged hazards and the lack of routine patrols are reasons authorities urge caution; visitors are advised to follow posted signage and local regulations before entering the water.
