Water Temperature: Daily Trends, Historical Records, and Forecast
❌ 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
Fremont Lake in Wyoming is a high-elevation lake whose surface temperatures reflect its mountain setting and seasonal weather. In winter the lake is commonly at or just above freezing, around 32–36°F (0–2°C) and often freezes over. Spring thaw pushes surface readings into the mid-30s to low-50s°F (2–10°C) depending on spring warmth. During the warmest part of summer, surface temperatures typically reach roughly 55–70°F (13–21°C) on sunny, calm days, though deeper water stays much colder. By early fall the surface cools again to roughly 40–55°F (4–13°C) as air temperatures drop and daylight shortens.
Swimming at Fremont Lake is generally possible from a legal standpoint in many public shore areas, but it is not a sustained warm-water swimming destination because of the cold temperatures and short season. The lake’s elevation and depth mean that even summer swims can be brisk, increasing the risk of cold-water shock and hypothermia; there are also few lifeguards or safety services at most access points. Visitors who choose to swim should be prepared for cold water, check local access rules and conditions, stay close to shore, and limit exposure time to reduce risk.
