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
New Brunswick, New Jersey, is situated along the Raritan River, which experiences temperature variations throughout the year. During the summer months, the water temperature in the Raritan River can range from 70°F to 80°F (21°C to 27°C), making it somewhat appealing for outdoor activities like kayaking or boating. However, despite the warmer temperatures, swimming in the Raritan River is not recommended for several reasons.
The river's water quality is often impacted by pollution from industrial, agricultural, and urban runoff, which can make it unsafe for recreational swimming. High bacteria levels and other contaminants are common in areas near urban centers like New Brunswick, posing health risks for swimmers. Additionally, the Raritan River has strong currents, making it challenging and hazardous to swim in certain sections of the river, particularly near bridges or industrial zones.
For those in New Brunswick seeking safe water activities, there are better alternatives available, including local public pools and nearby lakes that offer regulated swimming conditions. These options provide a more controlled environment where water quality is monitored regularly, ensuring a safer and more enjoyable experience for those looking to swim or engage in water-based recreation.
