This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used.

The Susquehanna River, one of the oldest and longest rivers on the East Coast, flows through New York, Pennsylvania, and Maryland, offering diverse landscapes and water conditions. The water temperature in the Susquehanna varies throughout the year, typically rising to around 60–70°F (15–21°C) in the summer months. This makes swimming possible and somewhat pleasant in the river’s calmer stretches, particularly in the more sheltered areas. During the winter, however, the water temperature drops significantly, often below 40°F (4°C), making swimming hazardous and generally impractical.

Swimming in the Susquehanna River is less common compared to other outdoor activities, but it is still enjoyed in certain parts, particularly in parks or designated recreational areas where the current is calmer. While some people may swim or wade in the river’s slower sections, swimmers need to be aware of the river's occasional strong currents, especially in the deeper, faster-flowing areas. The river’s water quality can also vary, influenced by urban and agricultural runoff, which can impact the overall experience. Despite these considerations, the Susquehanna is a popular spot for boating, fishing, and kayaking, offering a scenic environment for various water activities.
