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.

The Minnesota River, flowing through the state of Minnesota, is an important waterway with a mix of calm and fast-moving sections. The temperature of the river can vary widely depending on the time of year. In the spring, the water is usually quite cold, ranging between 40°F and 50°F (4°C to 10°C) due to snowmelt runoff. As summer arrives, the water warms up, reaching more comfortable swimming temperatures of 70°F to 80°F (21°C to 27°C) in some areas, especially in calmer stretches.
While swimming in the Minnesota River is not as popular as in other more designated swimming locations, it is possible in certain areas. The river’s slower, shallow regions can provide a refreshing swim during hot summer days. However, due to the river's strong currents and varying water levels, it’s important for swimmers to stay cautious. The water quality can sometimes be affected by agricultural runoff or heavy rains, so it's advisable to check local advisories before swimming. In addition to swimming, the Minnesota River is a prime spot for fishing, boating, and kayaking, drawing outdoor enthusiasts who enjoy the scenic views and recreational opportunities the river offers.
