Water Temperature in New Jersey: General Trends and Swimming Opportunities

New Jersey's coastline along the Atlantic Ocean experiences a wide range of water temperatures throughout the year. During the summer months, the ocean temperature can reach around 70°F to 80°F (21°C to 27°C), making it comfortable for beachgoers and swimmers. These warmer waters are a significant draw for tourists during the summer season. In the winter, however, the water temperature drops significantly, often reaching 40°F to 45°F (4°C to 7°C), which is too cold for most people to enjoy swimming. This colder water is influenced by the North Atlantic currents and cooler weather patterns.

Inland lakes and rivers in New Jersey, especially those in the northern and central parts of the state, tend to have slightly different temperature patterns. During the summer months, freshwater lakes such as Lake Hopatcong can see water temperatures ranging from 70°F to 75°F (21°C to 24°C), offering ideal conditions for boating, fishing, and swimming. In smaller, more shallow lakes, water can warm up more quickly, reaching similar temperatures. However, these waters cool down rapidly in the fall, with lake temperatures often dipping to around 50°F to 60°F (10°C to 15°C) by October, making it less ideal for water activities.

Rivers in New Jersey, such as the Delaware River, have temperatures that fluctuate with the seasons. In the warmer months, the river water can reach about 60°F to 70°F (16°C to 21°C), providing a cool but comfortable setting for kayaking, tubing, and fishing. As temperatures drop in the fall and winter, river temperatures also decrease, often falling below 40°F (4°C), especially in the northern regions. These cold temperatures make the river less conducive for recreational swimming, but they do attract those interested in cold-water fishing or winter activities like ice fishing.
