*** 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
Cheney Reservoir’s surface water temperatures vary considerably through the year. In summer months, surface readings commonly reach the mid-70s to mid-80s °F (about 24–30 °C), with the warmest conditions typically in July and August. Spring brings a steady warm-up, with surface temperatures often ranging from the low 40s to mid-60s °F (roughly 5–18 °C) as snowmelt and cool rains moderate warming. In fall the water cools again, commonly sitting in the 50s to low 60s °F (10–17 °C) before winter, when surface temperatures frequently fall to near freezing and into the 30s to low 40s °F (0–5 °C); deeper water remains colder year-round. Weather, inflows, wind and water depth all influence local conditions, so small-scale variations are normal.
Swimming is generally permitted at Cheney because it is a public recreational reservoir, but opportunities are subject to practical limits and safety considerations. Many shoreline and park areas allow swimming access, yet lifeguards are not usually provided and conditions such as steep drop-offs, boat traffic, sudden temperature changes, and occasional algae or water-quality advisories can make open-water swimming risky. Visitors should follow posted notices, avoid blooms and runoff-affected water, and use appropriate safety gear or supervision when entering the reservoir.
