*** 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
Memorial Lake in Pennsylvania experiences typical seasonal variability for small, shallow northeastern lakes. In spring the surface water often ranges from about 45–65°F (7–18°C) as snowmelt and cool rains flush the basin. Summer brings the warmest conditions, with surface temperatures commonly between roughly 68–80°F (20–27°C) on warm days and occasionally rising into the low 80s°F (≈27–28°C) during heat spells; deeper water stays cooler. Autumn sees a steady cooling back into the 50–65°F (10–18°C) band, and in winter the lake can approach freezing, with surface readings near 32–40°F (0–4°C) and periods of ice cover depending on winter severity. Wind, recent weather, and depth all influence local readings, and temperature stratification can make deeper areas significantly colder than the surface.
Swimming at Memorial Lake is managed seasonally and is permitted only in designated, monitored areas when the park opens its beach facilities and water quality meets safety standards. Authorities restrict access outside those times because low temperatures, poor visibility, changing weather, and the potential for hypothermia or cold-water shock create hazards. During the approved season lifeguards or park staff may be present and rules such as no-swim advisories are used to protect visitors, so swimmers should follow posted guidance and check current conditions before entering the water.
