Water Temperature in Fresno: General Trends and Swimming Opportunities

Fresno, California, is situated near the San Joaquin River, which offers a variety of recreational opportunities, though swimming is not as common in the river compared to other water activities like fishing or boating. The water temperature in the San Joaquin River varies throughout the year, with the warmest temperatures typically occurring in late spring and summer. During the summer months, the water temperature generally ranges from 70°F (21°C) to 75°F (24°C). These temperatures can be relatively cool but still refreshing, especially considering the hot inland temperatures of Fresno, which often exceed 100°F (38°C). However, the current in certain sections of the river can be strong, which makes swimming a bit more challenging and potentially unsafe in some areas.

In the cooler months, the water temperature in the San Joaquin River drops considerably, typically ranging from 50°F (10°C) to 60°F (15°C). These cooler temperatures can make swimming uncomfortable, and most people tend to avoid entering the river during this time. The river’s flow can also be stronger in the winter due to seasonal runoff, further increasing the difficulty and risk associated with swimming.

Although the San Joaquin River may not be the primary destination for swimming, it is a popular location for other water-based activities such as kayaking, fishing, and wildlife observation. For those seeking a more controlled and comfortable swimming experience, Fresno has public pools that maintain a consistent water temperature year-round, typically between 78°F (26°C) and 82°F (28°C). These pools offer a more predictable environment for swimming, especially during the cooler months when the river is less inviting.
