*** 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
Corona, California, is located in the Inland Empire region, where water activities are often centered around local lakes, reservoirs, and nearby rivers. While the city itself does not have a prominent natural river running through it, it is close to several key bodies of water that offer opportunities for swimming and other recreational activities. The temperature of water in these areas can vary depending on the season. For instance, nearby lakes such as Lake Matthews and Prado Lake, which are often used for boating and fishing, can have water temperatures that range from 60°F (15°C) to 75°F (24°C) during the warmer months. These temperatures make them suitable for swimming, though they are still relatively cool compared to ocean water.
In the summer months, the water in these lakes and reservoirs can become warmer, especially in shallower areas, with temperatures sometimes reaching 80°F (27°C). This makes the lakes more comfortable for swimming and picnicking, providing a great way to cool off from the typical inland heat, where temperatures can exceed 100°F (38°C). However, the water can feel chilly in some deeper areas or parts of the reservoir where the water flow is more constant, particularly in the early spring or late fall when temperatures dip.
During the cooler months, the water temperature in these bodies of water drops, typically ranging from 50°F (10°C) to 60°F (15°C), which makes swimming less appealing for most people. The colder temperatures, combined with the lower water levels in some reservoirs during winter, can make these areas less suitable for swimming, though they remain popular for other activities like hiking and wildlife watching. For those seeking warmer swimming conditions year-round, nearby public pools in Corona maintain a comfortable water temperature, typically between 78°F (26°C) and 82°F (28°C), offering a more controlled environment for swimming.
