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.

*** 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
Rye Patch Reservoir on the Humboldt River experiences wide seasonal swings in surface water temperature. In winter, surface temperatures commonly hover near freezing to the mid‑40s °F (about 1–7 °C). Spring warming typically brings surface readings into the mid‑40s to mid‑60s °F (7–18 °C). Peak summer surface temperatures often reach the low 70s to mid‑80s °F (around 21–29 °C) on warm, calm days, while autumn sees a decline back toward the 50s–70s °F range (10–21 °C). Temperatures vary with depth, inflow from the Humboldt River, wind and weather; deeper water and shaded areas remain much colder than the surface, and sudden cold layers can persist even in summer.
Swimming at Rye Patch is generally allowed as part of the Rye Patch State Recreation Area’s day‑use activities, and beaches and boat launches provide access. However, there are no widespread lifeguard services, water levels can drop or expose hazards, and boat traffic can create safety concerns. Cold shock from cooler water, submerged debris, and occasional water‑quality advisories are reasons to exercise caution. Visitors should check on local conditions, avoid alcohol, wear flotation as appropriate, and prefer warmer summer months for more comfortable and safer swimming.
