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
Robert S. Kerr Reservoir typically follows the seasonal temperature patterns common to large, lowland reservoirs in eastern Oklahoma. In spring (March–May) surface temperatures generally run about 50–70°F (10–21°C) as the water warms; summer (June–August) is the warmest period with surface readings often between 75–90°F (24–32°C), especially in shallower bays and near shore. In early fall (September–November) temperatures usually fall back into the 60–75°F (16–24°C) range as cooling begins, and winter months (December–February) commonly see surface temperatures around 35–50°F (2–10°C). Deeper channels and parts of the reservoir can remain several degrees cooler than surface values, and local weather, inflows, and wind can cause significant day-to-day variation.
Swimming is generally permitted in many parts of Robert S. Kerr Reservoir and nearby recreation areas, but it is not universally supervised or restricted; designated beaches or park areas may be safer choices because they have clearer access and fewer boats. Caution is advised because of boating traffic, submerged hazards, sudden drop-offs, currents near the dam or navigation channels, and the occasional water-quality advisory such as algal blooms. Visitors should choose marked swimming areas when available, follow posted rules, and check local conditions before entering the water.
