*** 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.

Location & Local Information
Harlem, located in the northern part of Manhattan, sits along the banks of the Hudson River, offering a beautiful view of the river but also presenting challenges for water-based activities like swimming. The temperature of the Hudson River near Harlem can vary significantly depending on the season. During the summer, the water temperature typically hovers between 65°F and 75°F (18°C to 24°C), making it more comfortable for water activities, though it can still feel a bit cool, especially with the river's currents. In winter, temperatures drop significantly, and the water can be as cold as 40°F (4°C), making swimming in the river impractical and dangerous.
Swimming in the Hudson River near Harlem is not recommended due to the strong currents and heavy boat traffic. The river is navigable, and it's often crowded with commercial vessels, ferries, and recreational boats, which can make it unsafe for swimmers. The water quality has improved in recent years, but pollution from industrial runoff and boat waste remains a concern. Additionally, the river's currents can be unpredictable, particularly in areas with bridges and piers like those near Harlem.
For those who want to enjoy the river safely, there are other activities like kayaking or paddleboarding, which are more commonly done in the Hudson River near Harlem. The city's various waterfront parks, like the Riverbank State Park, provide scenic views and recreational spaces where you can relax by the water, without the risks of swimming in it. If you're specifically looking for a safe, designated swimming area, you would need to head to one of New York's many public pools or beaches, as the Hudson River in Harlem is primarily for boating and sightseeing rather than swimming.
