Water Temperature in Allentown: General Trends and Swimming Opportunities

The temperature of the river water in this area is typically cool, especially during the spring and fall seasons. During summer, the water temperature generally ranges between 60°F and 70°F (15°C to 21°C). While this range may feel refreshing, it is too cold for comfortable, extended swimming for most people. The temperature fluctuates with seasonal changes, and colder temperatures are common during the early spring and late fall due to upstream water flows and weather patterns.
Swimming in the Lehigh River in Allentown is not a popular activity, mainly because of the river’s cold water and fast-moving currents. While some may choose to wade in the shallower, calmer sections, swimming is not generally recommended due to safety concerns related to the currents and the river's overall flow. The Lehigh River, especially in Allentown, is better known for activities like kayaking, fishing, and canoeing, which are enjoyed by residents and visitors in various sections of the river. The natural beauty and recreational potential make it a great spot for these activities, but the conditions are less ideal for swimming.
