*** 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
Silver Lake in Washington typically has cool water year-round, with temperatures that vary by elevation, depth and recent weather. In winter the surface often hovers just above freezing, roughly 33–40°F (1–4°C). During spring and early summer it warms into the 40s and lower 50s Fahrenheit (about 4–12°C) as snowmelt and rain continue to feed the lake. Peak summer surface temperatures commonly reach the 60s to low 70s °F (15–23°C) on warm, calm afternoons in shallower areas, while deeper sections remain notably colder. In autumn the water cools again, generally falling into the mid-40s to mid-50s °F (7–13°C) as air temperatures decline and daylight shortens.
Swimming is generally permitted at many Silver Lake access points and is a common recreational activity in summer, but whether it’s allowed at a specific site depends on local management, posted rules and water quality conditions. Authorities may close or discourage swimming because of low temperatures that create cold-shock or hypothermia risk, bacterial contamination, harmful algal blooms or boat traffic hazards. If you plan to swim, follow posted signage, respect any designated swim areas, be aware of swift temperature changes with depth and check current local advisories for safety and water-quality information.
