*** 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
Lake Pleasant, located north of Phoenix in the Sonoran Desert, is a large reservoir that serves as a vital water supply and a major recreational hub. Its water temperatures fluctuate dramatically in response to the desert climate. During the peak summer months, surface temperatures are generally very warm, ranging from 27∘C to 29∘C (80∘F to 85∘F), making the water ideal for cooling off. Conversely, in the winter, the water cools significantly, with temperatures typically dropping into the range of 10∘C to 16∘C (50∘F to 60∘F), which is generally too cold for casual swimming.
Swimming is widely permitted and popular at Lake Pleasant, as the Maricopa County Parks and Recreation Department encourages water-based recreation. Visitors often swim in calmer areas like Fireman's Cove and Coles Bay, and the two marinas on the lake even feature large, inflatable water parks with lifeguard staff during the summer season. However, most swimming is done at one's own risk as there are no official lifeguarded beaches. Swimmers are advised to use caution because the lake is man-made, meaning water depth fluctuates dramatically, and the sudden drop-offs into cooler water can pose a thermal shock hazard, especially for inexperienced swimmers.
