Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 79°F (26°C) to 82°F (28°C). This is very warm water, allowing for extended stays without any discomfort. Swimming in these conditions will be particularly enjoyable, making it the ideal temperature range for those who want to relax in the sea. Additionally, water in this temperature range is suitable for children and elderly people, as it is comfortable for prolonged stays. 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.

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.
