*** 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 of Gunnison Reservoir in Utah experiences a wide annual swing in water temperature driven by elevation and seasonal weather. In spring the surface water commonly ranges from about 40–55°F (4–13°C) as snowmelt and cool nights keep temperatures low. During summer the warmest, sheltered shallow areas often reach roughly 65–75°F (18–24°C), and on unusually hot days small bays can briefly approach 75–80°F (24–27°C), while deeper water remains markedly cooler. In autumn surface temperatures generally fall back to the 50–60°F (10–16°C) range, and winter brings very cold conditions with water near freezing, roughly 32–40°F (0–4°C), and ice forming in some years.
Swimming at Lake of Gunnison Reservoir is typically allowed but is largely informal and subject to local rules and seasonal conditions. People do swim there in summer when surface temperatures are most comfortable, but cold-water shock and rapid heat loss are real hazards outside midsummer, and there are often no lifeguards, limited shoreline facilities, boat traffic, and variable water quality after runoff events. For safety, swimmers should heed posted regulations, avoid solitary swims, consider protective wetsuits in cooler periods, and be mindful of boats and sudden drop-offs.
