*** 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
Lake McAlester’s surface water temperatures vary with the seasons and weather, as is typical for a shallow-to-moderate depth reservoir in eastern Oklahoma. In spring the lake commonly warms from roughly 50–70°F (10–21°C) as air temperatures rise and runoff subsides. Summer brings the warmest conditions, with surface readings often in the 75–85°F range (24–29°C) and occasional peaks into the mid-80s to around 86°F (30°C) during hot spells. After the peak season, temperatures usually fall in autumn to about 60–75°F (16–24°C). Winter surface temperatures commonly drop to roughly 35–50°F (2–10°C), with colder pockets at depth and faster cooling after cold fronts. Localized factors such as wind, inflows, and depth mean temperatures can vary across the lake and by time of day.
Swimming at Lake McAlester is generally permitted as a recreational use of the reservoir, but opportunities depend on site-specific conditions and management rules. Designated swim spots may be limited and there are typically no lifeguards, so visitors should heed posted signs, water-quality advisories, and algae or blue-green algae warnings that can close areas. Comfort and safety also change with temperature: many swimmers find water above about 70°F (21°C) pleasant, while water below 60–65°F (15–18°C) can cause cold shock and increase hypothermia risk, so exercise caution and check local guidance before entering.
