*** 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 McConaughy is a large reservoir on the North Platte River whose surface temperatures vary substantially through the year. In spring the water is typically cool, often in the 40–60°F range (4–16°C) as snowmelt and inflow keep temperatures low. By summer surface conditions warm, with many areas commonly reaching 65–80°F (18–27°C) and, in shallow bays on hot afternoons, occasionally a few degrees warmer. Autumn brings a steady cooling back toward 50–65°F (10–18°C), and winter waters hover near freezing in shallower parts and generally range from about 32–45°F (0–7°C) depending on ice, wind and inlet flows. Because the lake is large and relatively deep in places, temperatures can show considerable variation between shallow shoreline zones and deeper open-water areas.
Swimming is allowed at Lake McConaughy within the state recreation areas and on beaches managed for public use, because the reservoir is a designated recreational facility with maintained access and amenities. However, swimmers should be aware of hazards: there is no widespread lifeguard coverage, boat traffic and sudden drop-offs occur, and cooler or rapidly changing temperatures can increase risk of hypothermia or difficulty. Water quality is monitored but can change with runoff and algal conditions, so visitors are advised to follow posted guidance, choose designated swim areas, and consider seasonal temperatures when planning to enter the water.
