*** 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
Grass Pond in New York typically follows the seasonal pattern of small inland ponds in the region, with surface temperatures varying widely through the year. In winter the surface sits around freezing, about 32°F (0°C), and often freezes over. Spring temperatures commonly rise from roughly 35–55°F (2–13°C) as the ice clears and the water slowly warms. By midsummer shallow areas can reach comfortable swimming temperatures, often about 60–75°F (16–24°C), with the warmest spots occasionally touching the upper 70s°F (around 25°C) on hot, calm days. In autumn the pond cools again, generally falling into a range near 45–65°F (7–18°C) before ice formation begins.
Swimming is possible in many New York ponds including Grass Pond where public access and conditions allow, but whether it is formally permitted depends on land ownership, local regulations, and posted signs. Water quality, sudden temperature changes, and hidden underwater hazards can affect safety: cold spring or fall water can cause cold-water shock, and winter ice is hazardous. Because smaller ponds warm unevenly, shallow bays are friendlier for casual swimming while deeper spots stay chilly. Visitors should confirm access and advisories with local authorities and use appropriate precautions for temperature and water conditions.
