Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Des Plaines, Illinois, is located near the Des Plaines River, which flows through the area, offering a scenic backdrop for the city. The river itself is not typically known for being a major swimming destination, as the water can be murky and subject to fluctuating conditions. The water temperature in the Des Plaines River varies with the seasons. During the summer months, the temperature can range from 70°F to 75°F (21°C to 24°C), which may be somewhat comfortable for wading or cooling off, but it is generally not considered ideal for long swims.
While the river provides opportunities for activities such as fishing, kayaking, and canoeing, swimming in the Des Plaines River is not a common or recommended activity due to water quality concerns and potential hazards such as strong currents, debris, or pollution. Local authorities tend to caution against swimming in the river, advising visitors to enjoy the natural beauty of the area through other outdoor activities.
During the colder months, the water temperature in the Des Plaines River drops significantly, often ranging from 35°F to 45°F (2°C to 7°C). This makes swimming even more impractical, as the river becomes too cold for most people to enter safely. Despite the lack of widespread swimming opportunities, the river and its surrounding parks provide a peaceful setting for walking, birdwatching, and nature enjoyment.
