*** 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
Alloway Lake in southern New Jersey experiences typical temperate freshwater seasonal changes in surface water temperature. In winter the surface commonly approaches freezing, roughly 32–40°F (0–4°C), and may form ice in prolonged cold spells. Spring sees a steady rise, often between 45–66°F (7–19°C) as the lake mixes and warms. By summer, surface temperatures are usually most comfortable for recreation, frequently ranging from about 70–82°F (21–28°C) on warm afternoons, though shallow bays can warm more and deeper water remains noticeably cooler. In autumn the lake cools again, with surface readings commonly falling into the 50–70°F (10–21°C) range as air temperatures decline and turnover begins.
Swimming at Alloway Lake is typically possible during the warm months where public access points or designated beaches exist, because summer surface temperatures reach ranges tolerable for recreational bathing and lifeguarded areas may be provided. Whether swimming is allowed at any specific spot depends on local rules, ownership (some shoreline is private), posted signage, and current water-quality advisories. Safety considerations include colder water at depth, variable currents or vegetation, and seasonal algal blooms; visitors should check local guidance, heed posted restrictions, and avoid entering the water when advisories or warnings are in effect.
