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 Moreau River, located in South Dakota, is a smaller waterway that winds through the scenic landscapes of the state. The water temperature in the Moreau River can fluctuate significantly depending on the time of year. During the colder months, particularly in late fall and winter, the water temperature can drop to well below 40°F (4°C), making swimming unfeasible and even dangerous. In spring and early summer, snowmelt from surrounding areas can cause the water to rise and remain cold, ranging from 45°F to 55°F (7°C to 13°C), which can still make swimming uncomfortable for most people.
As summer progresses, the water temperature in the Moreau River gradually warms up, reaching more comfortable levels, typically between 60°F and 75°F (15°C to 24°C) in the warmer months. This temperature range can make swimming more feasible, particularly in the calmer sections of the river. However, due to the river’s relatively remote location and lower popularity compared to larger rivers, it does not have widespread facilities or established swimming areas. Additionally, the river can have strong currents and varying depths, which could pose potential risks for swimmers. Those who do choose to swim should be cautious, aware of their surroundings, and make sure to check the water conditions before entering. For those looking for a more serene experience, kayaking and fishing are also common activities along the Moreau River, which offers a quieter, less crowded alternative to other local rivers.
