Water Temperature in San Bernardino: General Trends and Swimming Opportunities

San Bernardino, California, is located near the Santa Ana River, which flows through the region. While the river offers opportunities for activities like fishing, hiking, and bird watching, it is generally not a popular location for swimming due to its water temperature and current conditions. During the summer months, the water temperature in the Santa Ana River typically ranges from 60°F (16°C) to 70°F (21°C). Although this can be refreshing on a hot day, the cooler temperatures, combined with the river's strong current, make it less ideal for casual swimmers.

The river’s water temperature drops further during the winter months, usually ranging from 50°F (10°C) to 60°F (15°C). These colder temperatures make swimming even less appealing. Additionally, the Santa Ana River can be fast-moving in some areas, especially after rainfall or during higher water flow periods, which can present a safety hazard for swimmers. While the river is scenic and offers a peaceful environment for other outdoor activities, such as kayaking and tubing, it's not typically a place for extended swimming.

For more suitable swimming options, residents and visitors to San Bernardino can head to local public pools or nearby lakes. Public pools in the area usually maintain temperatures between 78°F (26°C) and 82°F (28°C), making them more comfortable for swimming. Additionally, nearby reservoirs like Lake Arrowhead and Big Bear Lake offer warmer waters, especially in the summer, making them more popular destinations for swimming, boating, and fishing. These alternative locations provide a safer and more enjoyable swimming experience compared to the Santa Ana River.
