*** 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
Tucson, Arizona, is situated along the Santa Cruz River, a waterway that runs through the region, though it’s not typically known for being a prime location for swimming. The river itself is often shallow and can fluctuate significantly in terms of water flow, depending on the time of year and rainfall. During the warmer months, the water temperature in the Santa Cruz River can reach around 70°F (21°C) to 80°F (27°C), which might be comfortable for short dips or cooling off. However, the water quality can vary, and some areas might not be as inviting for swimming due to the shallow, slow-moving nature of the river in Tucson.
In the cooler months, the water temperature tends to drop, usually ranging from 50°F (10°C) to 60°F (15°C), making swimming much less appealing unless you're prepared for cold water. Because the Santa Cruz River often experiences lower flow rates and can dry up or become very shallow in certain areas, it’s important to note that swimming opportunities can be limited, especially outside of the wetter seasons. The river is more commonly used for other activities, such as bird watching, hiking, and photography, given its natural beauty and proximity to the desert landscape.
While the Santa Cruz River may not be the ideal spot for regular swimming, Tucson offers plenty of alternatives, including community pools and nearby lakes that are better suited for water activities. For those looking to enjoy the outdoors and water-based fun in Tucson, public pools maintain a consistent water temperature of 78°F (26°C) to 82°F (28°C), providing a more comfortable and controlled environment for swimming.
