The Ill River, flowing through the Alsace region in northeastern France, is a picturesque waterway that passes by scenic towns like Strasbourg. Its water temperatures vary significantly with the seasons, typically averaging between 8-15°C (46-59°F) from autumn to early spring, and reaching a warmer 18-22°C (64-72°F) during the height of summer. These seasonal variations make the Ill River an appealing, though limited, spot for swimming primarily in the warmer months. However, as a river that passes through urban and agricultural areas, the Ill is subject to varying water quality levels, which can impact its suitability for recreational activities, including swimming.

While swimming is possible in certain areas, many locals and visitors prefer nearby designated swimming spots, as portions of the river may not always meet optimal standards for water quality. Some areas along the Ill also have currents or access restrictions, so it is recommended to swim only in approved zones or to explore nearby recreational facilities that offer safer, monitored swimming environments. In Strasbourg, for example, locals often enjoy the banks of the Ill for picnicking, kayaking, or boat tours, while dedicated swimming spots are available nearby in supervised public lakes.
