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.

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
Elmer Thomas Lake in southwestern Oklahoma experiences the same seasonal swings in water temperature typical of regional reservoirs. In summer the surface commonly warms into the mid-70s to mid-80s °F (about 24–29 °C), and during heat waves can approach the upper 80s °F (around 31–32 °C). Spring and fall see more moderate temperatures, roughly 50–70 °F (10–21 °C) as the water transitions between seasons. Winter surface readings often fall into the mid-30s to high 40s °F (about 2–9 °C), with colder snaps pushing temperatures lower near freezing in shallow patches. Deeper or shaded areas will remain cooler year-round and the lake can stratify in summer, producing a range of temperatures from surface to bottom.
Swimming at Elmer Thomas Lake is generally possible but not heavily supervised; there are few if any staffed lifeguard beaches, and access is typically subject to park rules, seasonal closures, and water-quality advisories. Because temperatures can be chilly outside the summer months and sudden drops in water temperature increase the risk of cold-water shock, most recreational swimming is concentrated in the warmest weeks of summer. Boating traffic, algae blooms after warm spells, and the lack of formal swim facilities mean swimmers should exercise caution, check local conditions, and treat swimming as a self-responsible activity.
