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 Musselshell River, located in central Montana, is a peaceful, meandering river that provides a tranquil setting for outdoor activities. Water temperatures in the Musselshell vary significantly throughout the year. During the spring, the river is typically colder, with temperatures hovering around 40°F to 50°F (4°C to 10°C), due to snowmelt from the surrounding mountains. These temperatures make swimming in the river less comfortable for most people during this time of year.
As the summer months arrive, the water temperature in the Musselshell River increases, reaching a more inviting range of 60°F to 70°F (15°C to 21°C), making it more suitable for swimming. Although the river is relatively shallow in some sections, the current can be swift in certain areas, which may affect swimming safety. Some spots along the river have calmer, slower-moving waters, which are generally safer for swimming and wading. However, due to the river's rural location, it is less crowded compared to more popular swimming destinations, offering a quieter and more serene experience for those who seek a natural, off-the-beaten-path location for a swim. Swimmers should still exercise caution, as the river can contain hidden rocks and debris, especially during higher water levels.
