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 Overholser’s surface water temperatures follow Oklahoma’s seasonal cycle. In winter months (December–February) surface readings commonly fall in the mid-30s to mid-40s °F (about 1–7 °C). Spring (March–May) sees a steady rise, often ranging from roughly 50–65 °F (10–18 °C) as air temperatures warm and runoff changes. Peak summer values (June–August) can reach the mid-70s to mid-80s °F (around 24–29 °C), with occasional hot spells pushing surface readings toward 86 °F (30 °C). During autumn (September–November) temperatures typically decline into the 60s to low 70s °F (16–22 °C). Actual temperatures vary by depth, time of day, recent weather, inflow, and sunlight, and localized conditions such as turbidity or algal mats can create cooler or warmer pockets.
Swimming at Lake Overholser is not supported by designated public beaches or lifeguarded areas, and local authorities and park signage often discourage or restrict swimming because of safety and water-quality concerns. Hazards include underwater debris, variable currents near the dam and inlets, poor visibility, and occasional algal blooms or elevated bacteria levels after heavy rains. Boating, fishing and shoreline recreation are common, but anyone considering entering the water should check current advisories and exercise caution.
