Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 65°F (18°C) to 68°F (20°C). This is already quite warm water, which is ideal for most people. Swimming becomes comfortable, and prolonged stays in the water do not cause discomfort. This temperature is perfect for family trips and for those who prefer warmer water. It is also comfortable for water sports such as surfing or swimming. 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
Specific, continuous monitoring data for Toulon Lake in Nevada are limited, so the temperature figures below are approximations based on typical behavior of small high-desert and mountain reservoirs in the region. In summer, surface waters can warm to roughly 68–80°F (20–27°C) on calm sunny days, making conditions more comfortable for recreational use. During spring and fall the lake commonly registers cooler surface temperatures in the neighborhood of 45–65°F (7–18°C) as air temperatures fluctuate and runoff cools shallow zones. In winter, especially at higher elevations or during cold snaps, surface temperatures may approach freezing, often ranging from about 32–40°F (0–4°C), with partial or full ice cover possible depending on local conditions.
Swimming is typically allowed at many public lakes in Nevada, but access and permitted activities at Toulon Lake depend on land ownership, signage, and current water-quality or safety advisories, so users should verify locally. Even when swimming is permitted, cold-water shock and sudden depth changes are real hazards outside the warmest months; hypothermia risk rises rapidly when water temperatures fall below roughly 70°F (21°C). Seasonal algal blooms, low water levels, or limited facilities can also affect safety and enjoyment, so swimmers should choose warm periods, wear a life jacket if appropriate, and follow any posted regulations.
