*** 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
Wawayanda Lake in northern New Jersey is a shallow, warm-water reservoir whose surface temperatures follow the region’s seasonal pattern. In winter the lake often chills to near freezing, roughly 33–40°F (1–4°C). Spring brings gradual warming, commonly 45–65°F (7–18°C) as stratification begins. Summer is when the lake is warmest: typical surface readings range from about 70–80°F (21–27°C), with shallow coves occasionally reaching the low 80s°F (28–30°C) on hot, calm days. In autumn the water cools again into the 50–65°F (10–18°C) band before the lake approaches winter conditions.
Swimming in Wawayanda Lake is generally possible during the warmer months, and people commonly swim from shore or small beaches and swim-friendly areas. Whether swimming is advisable depends on safety and water-quality conditions: some access points are unguarded, boat traffic can be present, and periodic advisories for algal blooms or bacteria may lead authorities to restrict swimming. For those planning to swim, it’s wise to use designated entry points, be aware that average summer temperatures are comfortable for recreational swimming, and heed posted signs or park updates about closures or hazards.
