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
Riverside, California, is located along the Santa Ana River, which provides a scenic backdrop for outdoor activities. While the river is known for fishing, kayaking, and hiking, it is not typically a prime location for swimming due to its water temperature and strong currents. The water temperature in the Santa Ana River tends to range between 60°F (16°C) and 70°F (21°C) during the warmer months. While this can be refreshing on a hot day, it is not generally warm enough for extended swimming, and the currents can be quite strong, especially in areas with steeper gradients or after rainfall.
During the cooler months, the water temperature in the river drops significantly, typically falling between 50°F (10°C) and 60°F (15°C), which makes swimming even less desirable. The swift current in some sections also poses a safety risk, particularly for inexperienced swimmers. Although the river offers a beautiful environment for nature walks and bird watching, it is not the ideal spot for a relaxing swim. People looking for a more comfortable swimming experience in Riverside typically turn to public pools or nearby lakes.
For swimming, Riverside residents often head to local pools, which maintain a temperature range of 78°F (26°C) to 82°F (28°C), making them much more suitable for year-round swimming. Additionally, nearby lakes like Lake Perris offer warmer waters during the summer, reaching temperatures between 70°F (21°C) and 80°F (27°C), making them more ideal for swimming, boating, and other water-based activities. These locations provide a safer and more enjoyable swimming experience compared to the Santa Ana River.
