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
Bartlett Lake, a large reservoir in the Tonto National Forest, Arizona, experiences extreme seasonal swings in water temperature characteristic of the Sonoran Desert. In the peak summer months, the surface water becomes exceptionally warm, often reaching highs of 28∘C to 31∘C (82∘F to 88∘F), making the water highly desirable for cooling off. Conversely, during the winter, the water cools significantly. While the air temperature remains mild, the lake's surface temperature typically drops into the range of 11∘C to 14∘C (52∘F to 57∘F), which is generally too cold for casual recreational swimming.
Swimming is widely permitted and popular at Bartlett Lake, as it is managed by the U.S. Forest Service for open water recreation. The lake is known for its gently sloping beaches and sandy shorelines in certain areas, such as Rattlesnake Cove and Bartlett Flat, which are frequently used as designated swimming spots safe from the main boat channels. There are no official lifeguarded areas, meaning all swimming is done at one's own risk. Caution is paramount due to heavy boat and watercraft traffic, especially during weekends, and the potential for submerged hazards like rocks and debris. Swimmers are advised to use the buddy system and wear life jackets, particularly in unsupervised locations.
