Water Temperature in Pennsylvania: General Trends and Swimming Opportunities

Pennsylvania, while not having a direct ocean coastline, offers water recreation opportunities along its rivers, lakes, and the shores of Lake Erie in the northwest corner of the state. In summer, Lake Erie's water temperature near Pennsylvania averages around 70°F to 75°F (21°C to 24°C), providing an enjoyable setting for swimming, kayaking, and boating. The shallow areas near the shore warm up more quickly, making them particularly inviting during late spring and early summer.

The state’s major rivers, such as the Susquehanna, Delaware, and Allegheny, have varying water temperatures depending on the season and location. In summer, river temperatures generally range between 65°F and 75°F (18°C to 24°C), with smaller, slower-moving tributaries warming slightly more. These conditions are ideal for activities like fishing, canoeing, and paddleboarding. However, water temperatures drop significantly in the fall, often ranging from 50°F to 60°F (10°C to 15°C), limiting recreational use to those prepared for colder water.

Pennsylvania’s many lakes, including those in state parks like Lake Wallenpaupack and Raystown Lake, also experience seasonal temperature fluctuations. During summer, these lakes typically reach temperatures of 70°F to 80°F (21°C to 27°C) in surface waters, making them popular for swimming and other water-based recreation. In contrast, fall and early spring temperatures drop into the range of 45°F to 60°F (7°C to 15°C), creating cooler conditions better suited for fishing and scenic boating rather than swimming.
