Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. 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.

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
Fish Lake sits at high elevation in central Utah, so its water stays relatively cool through the year. Typical surface temperatures in mid-summer generally run about 50–65°F (10–18°C), and on particularly warm, calm afternoons can approach the upper 60s°F (around 20°C). In spring and early summer, as snowmelt feeds the lake, surface temperatures are often in the mid-30s to mid-40s°F (1–7°C). By late fall the surface drops back toward freezing, and in winter the lake commonly freezes, with surface water at or below 32°F (0°C) beneath the ice.
Swimming at Fish Lake is allowed, but it is limited by the lake’s persistent chill and high-elevation weather. There are no widespread lifeguarded beaches, and the cold water increases the risk of shock and hypothermia even on warm days, so swims are usually brief and best taken in the warmest weeks of July and August. Visitors who choose to swim should watch weather changes, enter slowly to acclimate, and avoid long exposures; many people prefer boating or shoreline recreation while water temperatures remain cool for most of the season.
