Water Temperature in Joliet: General Trends and Swimming Opportunities

The water temperature in the Des Plaines River during the summer months typically ranges from 70°F to 80°F (21°C to 27°C), depending on the weather conditions. While this temperature range might seem appealing for swimming, the river's strong current and water quality make it less suitable for regular swimming activities. The river is often used for kayaking, fishing, and other water sports, with many people taking advantage of its scenic views and easy access points.

Joliet does not have public swimming areas in the Des Plaines River, as the river's swift currents can pose safety risks. Local authorities generally advise against swimming in the river, and public swimming is restricted to controlled, designated areas. The nearby parks and recreational areas do offer alternatives for water activities, such as fishing, boating, and canoeing, but they are not suitable for swimming. During the warmer months, when temperatures rise to around 75°F to 85°F (24°C to 29°C), many people prefer to visit local pools or nearby beaches instead of swimming in the river itself.

In terms of water temperature outside of the summer season, the Des Plaines River cools down considerably, especially in the fall and spring, with water temperatures typically dropping to around 45°F to 60°F (7°C to 16°C).
