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.

The Santa Cruz River in Arizona is a significant waterway that flows through the southern part of the state, including areas like Tucson. The river's water temperature can vary depending on the time of year and the location along its course. During the hot summer months, from June to August, the water temperature typically ranges from 70°F to 80°F (21°C to 27°C), which is relatively warm compared to other rivers in the region. However, due to the river's often shallow nature, low flow rates, and the presence of warm desert air, the water can feel quite warm, making it less refreshing for swimming compared to cooler rivers found in other parts of the country.
During the winter months, the water temperature in the Santa Cruz River cools to between 50°F and 60°F (10°C to 15°C), especially in areas where the flow is more limited. In these conditions, swimming becomes less appealing, as the water can feel cold and the currents may be more unpredictable. Additionally, the Santa Cruz River's water quality can be affected by runoff from urban areas, which can discourage people from swimming in certain parts of the river.
While the Santa Cruz River is not typically a prime destination for swimming, it does offer opportunities for other recreational activities such as hiking along its banks, birdwatching, and wildlife observation. Some areas may have deeper pools or calmer stretches where people might wade or cool off, but in general, people visiting the river are more likely to engage in activities like kayaking or simply enjoying the surrounding desert landscape rather than swimming in the river itself.
