*** 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.

The Santa Clara River in Southern California flows through the foothills and valleys of the region, offering scenic views and a variety of outdoor activities. The water temperature in the river can vary depending on the season and the elevation of different stretches. During the hot summer months, the water temperature typically ranges from 65°F to 75°F (18°C to 24°C), which can provide a refreshing break from the heat. However, the Santa Clara River is often characterized by variable flow rates, especially as water is released from reservoirs upstream or after rainstorms, which can affect the river's current and water quality.
In addition to fluctuating water temperatures, the Santa Clara River is known for having sections with fast-moving water and occasional shallow pools. This can make swimming less predictable, especially in areas with stronger currents or deeper pockets of water. The river's flow can change rapidly, and its water clarity is often impacted by runoff, which can make swimming less desirable or even risky in certain areas. That said, there are some more tranquil sections where people can wade or swim safely, especially during calmer periods in the late summer and fall.
Although swimming in the Santa Clara River may not always be ideal due to variable currents and water conditions, it remains a popular spot for other outdoor activities. Kayaking, fishing, and hiking along the river are some of the primary ways visitors engage with the area. For those specifically looking to swim, nearby lakes and recreational areas may offer safer and more consistent conditions for a refreshing dip.
