This page provides information on the current water temperature in the Mississippi River, trends, monthly ranges and the forecast for the coming days.
Current Water Temperature
Water Temperature in the Mississippi River today is 35°F.
Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast
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 Mississippi River, one of the longest rivers in North America, stretches from Minnesota to the Gulf of Mexico, and its water temperature varies significantly depending on the region and the season. In the northern parts, like Minnesota, the water can be quite cold, especially in spring and early summer, with temperatures often ranging from 40°F to 60°F (4°C to 15°C). As the river flows southward, the water warms up, particularly in the summer months, where temperatures can reach between 70°F and 80°F (21°C to 27°C), making swimming more comfortable in these areas.
Swimming in the Mississippi River is possible, but it’s not as common as in other rivers with more designated swimming areas. In some regions, particularly in the southern parts and in quieter sections, people do swim, but the river's strong currents and sometimes unpredictable water conditions can make it dangerous. Swimmers are encouraged to be cautious, especially near industrial areas or where the river is more congested with boats. The river is also a popular spot for other recreational activities such as boating, fishing, and kayaking. For those looking to swim, it’s best to choose calmer parts of the river and make sure to stay aware of local safety recommendations.
