*** 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
Antioch, California, is located near the Sacramento River, a large waterway that offers some recreational opportunities, including swimming. The water temperature in the Sacramento River can vary significantly depending on the time of year. During the warmer months, from late spring to early fall, the water temperature typically ranges from 65°F (18°C) to 75°F (24°C). These temperatures can be relatively cool but still comfortable for short swims or wading, especially when the surrounding air temperatures in Antioch can soar above 90°F (32°C). However, the water can feel chilly compared to nearby lakes or ocean waters, which might limit swimming to certain parts of the river with calmer conditions.
In the cooler months, the water temperature of the Sacramento River drops considerably, typically ranging from 50°F (10°C) to 60°F (15°C). These lower temperatures can make swimming uncomfortable for most people, and the current may be stronger, further reducing the appeal of swimming. During this time, swimming is less common, and the river is more frequently used for fishing, boating, and wildlife observation.
While the Sacramento River may not be the top choice for year-round swimming, it offers a unique natural environment for those who enjoy water activities. For those seeking warmer and more controlled swimming conditions, Antioch has public pools and nearby lakes with more consistent water temperatures, offering a more comfortable environment for swimming year-round.
