Water Temperature in Bethlehem: General Trends and Swimming Opportunities
In Bethlehem, Pennsylvania, the Lehigh River flows through the city, providing a scenic backdrop and recreational opportunities. However, the temperature of the river water generally remains quite cold, especially in the spring and fall. During the summer months, the temperature of the Lehigh River typically ranges from 60°F to 70°F (15°C to 21°C), which is considered chilly for comfortable swimming. The river's water temperature is influenced by various factors, including upstream flows, the time of year, and weather conditions, with spring runoff from surrounding mountains making the water even colder early in the season.
While swimming is not commonly done directly in the river in Bethlehem, the Lehigh River is popular for other water activities such as kayaking, canoeing, and fishing. There are areas where people can wade or take part in recreational floating, but these activities usually occur in designated, calm sections of the river. Due to the fast-moving nature of the Lehigh River in certain areas, swimming can be risky because of potential currents. In general, it's recommended to avoid swimming in the river due to water quality concerns and the strong currents that can make it unsafe.
For those seeking better swimming options near Bethlehem, several nearby lakes and pools, such as those at local parks, offer more ideal conditions for swimming. The colder temperatures of the Lehigh River, combined with the natural conditions, make it more suited for activities like boating or scenic enjoyment rather than swimming.
