As of today, the minimum water temperature in the Hudson River ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

The Hudson River, stretching from the Adirondack Mountains in upstate New York to New York Harbor, is one of the most iconic rivers in the United States. Its water temperature varies significantly throughout the year, reflecting the seasonal climate changes of the region. In the winter and early spring, the river is quite cold, with temperatures ranging from 35°F to 50°F (2°C to 10°C). By late spring and summer, the water warms considerably, reaching 65°F–75°F (18°C–24°C) in many sections, especially in the lower Hudson near New York City and in calmer bays and tributaries.

Swimming in the Hudson River is possible but is generally limited to designated areas. Over the years, improvements in water quality have made recreational swimming more feasible in some sections of the river, particularly during the summer months when water temperatures are most comfortable. However, strong currents, boat traffic, and occasional water quality concerns make swimming in non-designated areas less advisable. Popular recreational activities along the Hudson include kayaking, paddleboarding, and riverside hiking, offering a variety of ways to experience this historic and scenic waterway.
