Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 79°F (26°C) to 82°F (28°C). This is very warm water, allowing for extended stays without any discomfort. Swimming in these conditions will be particularly enjoyable, making it the ideal temperature range for those who want to relax in the sea. Additionally, water in this temperature range is suitable for children and elderly people, as it is comfortable for prolonged stays. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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
The small reservoir along PA-799 typically follows the seasonal thermal patterns common to mid-Atlantic impoundments. Surface water in late winter and early spring often hovers near freezing up to about 33–45°F (0.5–7°C) as ice forms or thaws. By late spring temperatures commonly rise into the mid 40s to mid 60s °F (7–18°C), and in summer the upper layers can warm substantially, often ranging from roughly 68–80°F (20–27°C) on warm afternoons, especially in shallow bays. Deeper water remains markedly cooler year-round, and in summer the thermocline can create a sharp temperature contrast between warm surface water and colder depths below, which may stay in the 40s–50s °F (4–12°C).
Whether swimming is allowed at the PA-799 reservoir depends on local management and the reservoir’s purpose. If the impoundment serves as a drinking-water supply or lacks lifeguarded, supervised areas, swimming is frequently prohibited to protect water quality and reduce safety risks; conversely, some reservoirs permit swimming in designated areas during the warmer months when surface temperatures are comfortable. Health and safety concerns that influence access include bacterial or algal blooms, cold-water shock from sudden depth changes, underwater hazards, and the absence of rescue services, so visitors should follow posted rules and local authority guidance before entering the water.
