Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience. 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
Glenn Cunningham Lake, a reservoir in the Omaha, Nebraska area, follows typical Midwestern seasonal patterns for surface water temperature. In winter the lake commonly chills to near freezing, roughly 32–40°F (0–4°C), and may develop ice cover in sustained cold. During spring the surface warms through the 40–65°F range (4–18°C) as thaw and runoff continue. Peak summer surface temperatures often reach about 68–82°F (20–28°C), and during hot spells can climb into the mid-80s°F (around 29°C). In autumn the water cools back toward 50–68°F (10–20°C) as air temperatures drop. These figures are typical surface values; deeper water remains noticeably colder and local weather, wind, and solar exposure change conditions day to day.
Officially, Glenn Cunningham Lake is not managed as a designated public swim beach; posted rules and park policy restrict or discourage open-water swimming because the reservoir primarily serves flood control, boating and fishing, and lacks lifeguarded swimming areas. Concerns about water quality fluctuations, boat traffic, submerged hazards and seasonal algae also factor into prohibitions. Visitors commonly use the lake for fishing, boating and shoreline recreation, but anyone considering entering the water should observe on-site signage and local park or city guidance for current restrictions and safety information.
