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
In Trenton, New Jersey, the Delaware River runs along the city's border, offering picturesque views and some recreational activities. However, swimming in the Delaware River near Trenton is generally not recommended. The river's water temperature in the summer months can range from about 65°F to 75°F (18°C to 24°C), which might seem refreshing on a hot day, but the river's strong currents, high boat traffic, and occasional pollution make it an unsafe environment for swimmers.
While some areas of the Delaware River are used for water activities like fishing and boating, swimming is discouraged due to the risks associated with water quality and the river's natural flow. The river is known to have fluctuating water conditions, especially after heavy rains, which can lead to increased water turbidity and contamination. In addition, the fast-moving water and the presence of industrial and urban activities around Trenton can make it hazardous to swim in these waters.
For those looking to enjoy a swim in a safer environment, Trenton offers alternatives such as public pools, lakes, or nearby designated swimming areas. These locations are generally cleaner, safer, and better maintained for recreational swimming.
