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
Legg Lake in California typically shows clear seasonal variation in surface water temperature. In winter months the lake often cools to roughly 40–55°F (4–13°C). Spring sees a gradual rise, with surface temperatures commonly in the 50–65°F range (10–18°C) as the weather warms. Mid-summer is when the lake is warmest; surface readings frequently reach about 65–80°F (18–27°C) on sunny weeks, though exact values depend on air temperature, depth and inflow. By fall the water usually cools again, commonly falling into the 55–70°F bracket (13–21°C) before winter stratification breaks down. Deeper water stays colder year‑round, and short cold snaps or heavy rains can lower surface temperatures quickly.
Swimming at Legg Lake is generally permitted in designated areas when park rules and seasonal conditions allow, but it is subject to local regulation and safety advisories. Restrictions may be imposed for water‑quality concerns (such as algal blooms), hazardous boating traffic, lack of lifeguards, or dangerously cold temperatures that raise hypothermia risk. Visitors should check current posted rules, lifeguard availability and any advisories before entering the water; even in summer, cooler sub‑surface temperatures can make prolonged swimming uncomfortable or unsafe.
