Water Temperature in Wilmington: General Trends and Swimming Opportunities
The Delaware River, which runs through Wilmington, Delaware, is a major waterway that offers various recreational opportunities. However, when it comes to swimming, the river’s water temperature can be quite chilly, especially during the cooler months. In the winter and fall, the water temperature can drop to around 40°F (4°C), making it too cold for comfortable swimming. As spring arrives and the weather warms, the river's temperature begins to rise, typically reaching between 50°F (10°C) and 60°F (15°C) by late spring and early summer.
During the summer months, the water in the Delaware River can warm up to a more comfortable range of about 70°F (21°C) to 75°F (24°C), making it more suitable for swimming, especially in calmer sections of the river. However, due to the river’s strong current and industrial history, swimming in certain parts can be challenging and sometimes unsafe. Many people prefer to enjoy the river through activities like kayaking, canoeing, or boating rather than swimming, as the current and varying depths can make it difficult to safely swim in many areas.
For those looking for a more enjoyable and safer swimming experience, nearby lakes and pools are often preferred, as they tend to maintain more consistent and warmer temperatures, typically ranging from 70°F (21°C) to 80°F (27°C) in the summer. These locations provide an excellent alternative for those seeking a more relaxing swim without the concerns posed by the Delaware River's currents and varying water temperatures.
