The Lehigh River, winding through eastern Pennsylvania, is a beloved destination for outdoor enthusiasts, offering activities like rafting, kayaking, and fishing. The river’s water temperature varies depending on the season, with summer temperatures typically ranging from 65°F to 75°F (18°C to 24°C). During the cooler months, especially in spring and fall, the water can drop to between 50°F and 60°F (10°C to 15°C), while in winter, it can get much colder due to snowmelt and icy conditions.

While the Lehigh River is popular for its recreational offerings, it’s not widely considered a prime location for swimming. Many sections of the river feature strong currents, especially in the gorges and rapids, which can be hazardous for casual swimmers. In calmer areas, wading and cooling off are possible, particularly in stretches closer to recreational parks or access points with shallow water. However, the river’s primary appeal lies in its scenic beauty and the thrill of water sports rather than traditional swimming experiences.

For those seeking a more leisurely swim, nearby lakes or designated swimming areas might be a better option. The Lehigh River’s charm is in its dynamic flow, which makes it a favorite for whitewater adventures rather than tranquil swimming spots.
