*** 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
Sand Hollow Reservoir in southwestern Utah experiences a wide range of water temperatures through the year because of its desert climate and shallow, sun-warmed shallows. In winter the surface often cools into the 40s °F (about 4–10 °C), while spring warming typically brings surface temperatures into the 50s–60s °F (10–18 °C). By midsummer the reservoir commonly reaches its warmest levels, with surface waters frequently in the 70s and low 80s °F (around 21–28 °C), sometimes higher on hot, calm days. During autumn the water usually remains relatively mild, often cooling from the upper 60s into the 50s °F (about 16–12 °C) as air temperatures fall. Actual temperatures vary by depth, wind, and recent weather, so conditions can be cooler below the surface or after cold fronts.
Swimming is permitted at Sand Hollow and is a popular activity because of the sandy beaches and accessible shoreline, but users should follow park regulations and take normal safety precautions. There are designated beach and day-use areas but lifeguards are not always provided, and boat traffic, strong winds, and sudden temperature changes can create hazards, so wearing a life jacket, staying within marked areas, and checking current conditions are recommended before entering the water.
