*** 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
Lake of the Promised Land, in northeastern Pennsylvania, follows the typical seasonal pattern of small, forested reservoirs. Surface water temperatures in winter often hover at or just above freezing, roughly 32–40°F (0–4°C) when open water remains; spring brings a steady rise into the 40–60°F range (4–16°C) as the lake mixes and warms. In summer the measured surface tends to reach the warmest values, commonly 70–80°F (21–27°C) on average and occasionally into the low 80s°F (27–28°C) during heat waves, while deeper water stays markedly cooler. Autumn cooling returns surface temperatures to roughly 50–65°F (10–18°C) before winter ice formation.
Swimming is allowed seasonally at the state park’s designated beach area, where recreation is managed for public safety and water-quality considerations. The beach is typically staffed or monitored during the main summer season and is intended for surface swimming in the warmer months; outside the supervised zone and in deeper or colder parts of the lake, swimming is discouraged because colder, stratified water and underwater hazards can increase risk. Visitors should expect comfortable summer surface swimming but chilly conditions in early spring, late fall, or in submerged depths.
