The Passaic River, flowing through northern New Jersey, is a significant waterway with a history deeply tied to the region’s industrial development. Water temperatures in the Passaic River vary throughout the year, typically ranging from the mid-30s°F (around 1-3°C) in the winter to the 70s°F (21-25°C) during the summer. However, due to its urban surroundings, water conditions can be influenced by runoff and other environmental factors.

Swimming in the Passaic River is generally not recommended, primarily due to water quality concerns stemming from industrial pollution and contamination over decades. Efforts are ongoing to clean and restore parts of the river, but it is still more suited for activities such as boating, kayaking, and fishing in specific areas where conditions are safe. The river holds scenic spots, particularly away from densely urbanized zones, offering opportunities to enjoy its natural beauty from the shore or by watercraft rather than direct water immersion.
