Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. 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
Chimney Reservoir’s water temperature varies seasonally and with depth. In winter the surface often approaches near‑freezing, roughly 34–45 °F (1–7 °C), and spring warming typically brings temperatures into the 45–60 °F (7–16 °C) range. By summer, shallower, sun‑warmed areas can reach about 60–75 °F (16–24 °C), while deeper sections remain noticeably cooler. In autumn the surface usually declines again into the 50–65 °F (10–18 °C) band. These ranges fluctuate year to year depending on air temperature, inflows, reservoir level and local weather; colder, deeper water can persist even during warm months.
Swimming opportunities at Chimney Reservoir depend on local management and conditions. Many reservoirs in Nevada are managed for multiple uses and ordinarily permit swimming, but access may be limited by posted restrictions, water quality advisories, boat traffic, or safety concerns. Cold water temperatures—even in summer—can produce cold shock and increase hypothermia risk, and reservoirs often lack lifeguards or gradual shorelines, so caution is advised. Before swimming it’s best to check current rules and advisories, be aware of changing temperatures and depths, and use appropriate safety gear such as a life jacket if conditions or your swimming ability warrant it.
