*** 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

Salmon Falls Creek Reservoir typically shows marked seasonal variation in surface temperatures. In spring, as runoff and cooler air persist, surface water often ranges from about 40–60°F (4–16°C). By summer, the reservoir can warm considerably, with common daytime surface temperatures between roughly 65–85°F (18–29°C), especially in shallow bays on hot afternoons. Autumn brings a gradual cooling back into the 50–68°F (10–20°C) range as air temperatures drop and stratification breaks down. In winter the surface can fall to near freezing, often around 32–45°F (0–7°C), and in cold spells ice or slushy conditions may develop along protected shorelines.

Swimming at Salmon Falls Creek Reservoir is generally allowed as a recreational activity, and visitors commonly enter the water from beaches, boat launches, and shoreline areas. However, conditions vary and there are no widespread lifeguard services, so swimmers should be cautious about cold-water shock, changing depths, submerged hazards, and boat traffic. Water quality is usually acceptable for swimming but can be affected at times by algal blooms, runoff, or local advisories, so checking current conditions before entering the water is recommended for safety.
