Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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 McMurtry’s water temperatures follow the seasonal patterns typical of small reservoirs in north‑central Oklahoma. In spring (roughly March–May) surface temperatures commonly range from about 45–70°F (7–21°C) as the lake warms; in summer (June–August) surfaces often reach 70–86°F (21–30°C) at their warmest. During fall (September–November) temperatures cool back into the mid‑50s to mid‑70s °F (13–24°C), and in winter (December–February) surface water can fall to about 32–50°F (0–10°C). These are general surface values; deeper water remains cooler, and short‑term swings occur with cold fronts, hot spells, wind and rainfall, so measured temperatures vary by location and time of day.
Swimming at Lake McMurtry is not supported by a staffed or lifeguarded, designated beach area, so people who choose to enter the water do so at their own risk. The lack of formal swimming facilities reflects concerns about unmonitored water quality, submerged hazards, and limited emergency services rather than an absolute legal ban in all areas. In practice, most recreational water use is concentrated in the warmer summer months when surface temperatures are most comfortable, but visitors should exercise caution, check local signage or park rules, and be aware that conditions can change quickly.
