Water Temperature in Trenton: General Trends and Swimming Opportunities
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.

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.
