Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. 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.

*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

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.
