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
Bismarck, North Dakota, lies along the Missouri River, which offers scenic views and opportunities for outdoor recreation, though swimming is not as common in the river itself. The Missouri River, near Bismarck, is typically characterized by strong currents and variable water levels, which make it less suitable for recreational swimming compared to calmer lakes or designated swimming areas. The river is, however, popular for activities such as boating, fishing, and kayaking.
The water temperature in the Missouri River near Bismarck varies significantly depending on the season. During the warmer months, from late spring to early fall, water temperatures usually range from 60°F (15°C) to 75°F (24°C). In the summer, the water can warm up to about 70°F (21°C), which may be pleasant for boating or other water activities, but many locals and visitors prefer to swim in nearby lakes or dedicated swimming spots.
While swimming in the river near Bismarck is not typically recommended due to water conditions, there are some parks and beaches around the area, such as those at the Heart River or nearby lakes, that offer more suitable environments for swimming. These places provide calmer waters and designated swimming areas with lifeguards, making them safer and more inviting for swimmers during the summer months.
