*** Forecast - Our water temperature forecast
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
Pompton Lake, a man-made impoundment on the Pompton River in northern New Jersey, typically follows seasonal patterns familiar to small northeastern reservoirs. Surface temperatures in winter commonly hover near freezing into the low 40s °F (0–5 °C), with open-water periods usually above 32 °F (0 °C) except during brief ice formation. Spring warming moves surface water into the mid-40s to low 60s °F (7–17 °C) as runoff and air temperatures rise. Peak summer surface temperatures often range from roughly 70 to 78 °F (21–26 °C) on warm, calm days, while fall brings steady cooling into the 50s to mid-60s °F (10–18 °C). Local weather, depth, and sunlight exposure create short-term variability, and shallow near-shore areas warm or cool faster than deeper parts.
Public swimming opportunities at Pompton Lake are limited; there are no widely advertised designated beaches and swimming is generally not promoted by local authorities. Reasons include its role as a reservoir and recreational boating area, occasional water-quality issues such as runoff-driven turbidity or algal blooms, and the lack of lifeguard supervision and marked swimming zones. For safety, anyone considering entering the water should consult municipal guidance and be aware that conditions can change quickly with weather, boat traffic, and water-quality advisories.
