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
Piscataway, New Jersey, is situated along the Raritan River, a key waterway in the area. The water temperature in this section of the river varies throughout the year. During the summer months, temperatures typically range from 70°F to 80°F (21°C to 27°C), making it appear to be a good temperature for swimming. However, despite the relatively warm water in the warmer months, the Raritan River is not considered a safe location for recreational swimming due to a variety of factors.
The Raritan River near Piscataway often has strong currents and water quality concerns, which can make swimming dangerous. The presence of industrial activity, boat traffic, and runoff from surrounding urban areas can negatively affect water quality, with occasional contamination making it unsafe for swimmers. Additionally, the river's unpredictable currents and depth changes can pose risks to anyone attempting to swim in its waters.
As a result, swimming in the Raritan River in Piscataway is not recommended. Those seeking a safer and more controlled swimming experience are encouraged to use local pools or designated recreational areas in the area. These provide a safer and more enjoyable alternative to the river, with maintained facilities that ensure cleaner and calmer water for swimming.
