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
Opossum Lake in Pennsylvania typically follows the seasonal temperature patterns common to small northeastern lakes. Surface water in winter can approach freezing, roughly 32°F (0°C), with pockets of 30–34°F (−1 to 1°C) where ice forms. In early spring temperatures often sit in the mid‑30s to mid‑40s °F (1–7°C) as the lake stratifies. By late spring and early summer the surface commonly warms to about 50–70°F (10–21°C) depending on weather, and on warm, calm summer days surface readings can reach the low to upper 70s °F (21–26°C). As autumn progresses the surface cools again to the 50s and 40s °F (10–5°C). Deeper water remains colder year‑round, and conditions can vary with wind, sunlight, and recent precipitation.
Swimming at Opossum Lake is generally governed by local park rules and the presence of designated swimming areas; where an official beach is open during summer months, swimming is allowed because authorities monitor water quality and provide safety measures. In places without a designated beach, swimming may be discouraged or restricted due to submerged hazards, sudden depth changes, boat traffic, or variable water quality. In winter, ice cover makes swimming unsafe except for organized, supervised events. Visitors should check posted signs and local management information before entering the water.
