The Oude Maas is a distributary of the river Rhine in the southern Netherlands, flowing through the province of South Holland and passing through cities like Dordrecht and Vlaardingen. The water temperature in the Oude Maas varies seasonally, with summer temperatures typically ranging between 18°C and 22°C (64°F to 72°F). During the colder months, the temperature can drop significantly, with readings around 4°C to 7°C (39°F to 45°F) in early spring and late autumn. While the river's temperature is generally warm enough for swimming in the summer, it is still cooler compared to lakes or smaller rivers.

Swimming in the Oude Maas is not always recommended due to the strong currents, heavy commercial traffic, and industrial activity that characterize the river. The Oude Maas is an important waterway for ships, including large vessels and barges, which makes it potentially dangerous for recreational swimmers. In addition, the water quality in some areas may not always meet the safety standards for swimming. There are, however, designated swimming areas near recreational zones where water quality is monitored for cleanliness and safety. These areas are typically separated from the main shipping routes, ensuring safer conditions for swimmers.
