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
Foster Joseph Sayers Lake, an impoundment on Bald Eagle Creek in central Pennsylvania, experiences the typical seasonal swings of a temperate inland reservoir. In spring (April–May) surface temperatures commonly range from about 40–60°F (4–16°C) as runoff and cool air keep the lake brisk. During summer (June–August) the top layer warms to roughly 68–78°F (20–26°C), and on hot spells can approach the low 80s°F (27–29°C). Early autumn (September–October) sees cooling to approximately 55–70°F (13–21°C), while late fall and winter (November–March) often bring surface temperatures down toward 32–45°F (0–7°C) with ice possible in prolonged cold periods. Deeper water remains cooler year-round and stratification can create colder temperatures below the thermocline.
There is no formal, lifeguarded public swimming beach maintained at Foster Joseph Sayers Lake; people do swim there, but swimming is essentially at your own risk and subject to any temporary restrictions imposed by the managing agency. The lack of an official beach means limited safety infrastructure, and fluctuating water levels, submerged hazards, sudden drop-offs and cold-water or hypothermia risk can make unsupervised swimming hazardous. Visitors should check local notices, exercise caution, and wear personal flotation devices when appropriate.
