❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. 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
Wild Horse Reservoir in northeastern Nevada typically shows a strong seasonal swing in surface water temperatures. In winter the lake commonly sits at or just above freezing, roughly 32–40°F (0–4°C), and ice can form in cold spells. Spring brings a gradual warming with surface readings often in the 35–55°F range (2–13°C) as snowmelt and cool air persist. Peak warmth occurs in mid to late summer when shallow areas can reach about 60–75°F (16–24°C) on sunny days, though deeper sections remain noticeably cooler. By fall temperatures usually decline to roughly 45–60°F (7–16°C) as air temperatures drop and stratification breaks down.
Swimming at Wild Horse Reservoir is generally allowed because the site is managed as a recreation area and has accessible shoreline, but there are important caveats. There are typically no lifeguards on duty, water levels and conditions vary with seasonal releases and drought, and even summer swims can feel cold enough to increase the risk of cramping or hypothermia. Ice in winter and spring runoff in early season make swimming unsafe at those times. Visitors should check current local notices, respect any posted restrictions, and use caution—swimming is permitted but dependent on conditions and personal preparedness.
