*** 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
Millerton Lake’s surface water temperatures vary noticeably with the seasons. In summer months the lake commonly warms to roughly 70–82°F (21–28°C), which is comfortable for many swimmers. During spring and autumn the surface typically sits in the 55–72°F (13–22°C) range, cooling mornings and evenings and warming during the day. Winter temperatures drop further, often falling to about 45–55°F (7–13°C) at the surface. These figures are approximate and can change with weather, depth, and inflow conditions; deeper water and shaded coves remain colder year-round.
Swimming at Millerton Lake is generally permitted in the recreation areas and is a popular activity when conditions are suitable. Access is managed by the park, and swimming is allowed because the reservoir is maintained for public recreation, but it is often at your own risk; lifeguards are not consistently on duty and water conditions can be affected by cold pockets, currents, steep drop-offs, sudden depth changes, and boat traffic. Visitors should check local postings for any temporary restrictions, be aware of seasonal temperature swings that increase cold-water shock risk, and use caution when entering the water.
