*** 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
Lily Lake in Pennsylvania typically follows the seasonal temperature patterns of small temperate lakes. In summer the surface water commonly warms to roughly 70–85°F (21–29°C), making the upper layer comfortable for brief immersion and swimming on warm days. Spring temperatures usually range from about 40–65°F (4–18°C) as the lake stratifies and warms, while fall sees a cooling trend into the 45–65°F (7–18°C) bracket as surface waters lose heat. In winter the surface generally approaches freezing, around 32°F (0°C), and lakes in the region often develop ice cover, with actual under-ice temperatures just above 32°F (0°C).
Whether swimming is allowed at Lily Lake depends on local ownership and management rather than the water temperature alone. Where a lake has a designated public beach or park facility, swimming is typically permitted because authorities monitor safety and water quality; in other settings, swimming may be restricted or discouraged to protect drinking-water intakes, wildlife habitat, or for liability and safety reasons. Even when permitted, water quality advisories, currents, submerged hazards and seasonal cold shock should be considered; summer is the most comfortable season for swimming, while spring, fall and winter conditions make recreational swimming inadvisable or unsafe.
