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
Saint Paul, located at the confluence of the Mississippi and Minnesota Rivers, is an area known for its scenic riverfront and outdoor recreational opportunities. While the Mississippi River in the city is a popular destination for boaters, kayakers, and fishermen, swimming in the river is generally not advised. The water in this part of the Mississippi can be fast-moving and potentially hazardous due to strong currents, especially near locks and dams. The temperature of the river water in Saint Paul during summer months typically ranges from 60°F to 75°F (15°C to 24°C), which may be refreshing but does not create ideal swimming conditions due to its swift flow and water quality concerns.
Although swimming in the river itself is not recommended, Saint Paul has numerous other opportunities for water recreation. The city is home to several lakes and designated swimming areas, including Lake Como and Phalen Lake. These lakes provide calm, clean waters ideal for swimming, as well as public beaches that are monitored for safety and water quality. These areas are the go-to spots for residents and visitors looking to enjoy a safe and pleasant swimming experience.
While the Mississippi River in Saint Paul offers a beautiful setting for boat tours and scenic walks along the riverfront, those seeking a more tranquil swimming experience typically turn to local lakes or other managed swimming areas in the city. The river remains a prime location for water sports like canoeing, kayaking, and paddleboarding, where enthusiasts can take advantage of the river’s vast expanse while staying safe.
