*** 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
Sherman Lake in California typically experiences noticeable seasonal shifts in surface water temperature. In winter months the lake often cools to roughly 40–50°F (4–10°C), making the water quite chilly. Spring sees a gradual warming to about 50–60°F (10–16°C) as longer days and runoff raise surface temperatures. Peak summer conditions commonly bring surface readings in the mid-60s to mid-70s °F (around 18–24°C), and on warm, calm afternoons parts of the lake can reach the upper end of that band. In fall the water usually cools back into the mid-50s to mid-60s °F (13–18°C). Local factors such as recent rainfall, snowmelt, wind, depth and thermal layering mean temperatures can vary across the lake and at different depths.
Swimming at Sherman Lake is possible in many seasons but is often dependent on safety, water quality and local regulations. Summer is the most comfortable for recreational swimming because surface temperatures are highest, yet visitors should watch for cold pockets in deeper or shaded areas, boat traffic and sudden weather changes. Authorities may restrict or advise against swimming during algal blooms, high bacterial counts, or when hazardous conditions exist, so checking current lake advisories and using common-sense precautions—life jackets, swimming in designated areas, and avoiding sudden immersion into cold water—is recommended.
