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 Tongue River, flowing through southeastern Montana and northern Wyoming, is a relatively small river that is known for its clear waters and scenic landscapes. Due to its location in the northern United States, the water temperature in the Tongue River tends to stay on the cooler side. During the summer months, the water temperature can reach about 60–70°F (15–21°C), which is refreshing for a quick swim but might feel chilly for extended periods of time. In the cooler months, the river's temperature drops even further, making swimming impractical.
Swimming in the Tongue River is not as common as other activities like fishing, kayaking, or hiking, as the river is often characterized by faster currents, especially during spring snowmelt. While there are calmer stretches where wading and short dips may be possible, caution is recommended. The water can be quite cold and may carry hidden hazards such as rocks or sudden drops in depth. The river is more commonly used for canoeing and fishing, as it offers a peaceful, remote setting surrounded by the rugged beauty of the region.
For those interested in enjoying the water, the Tongue River offers opportunities for canoeing and tubing in the slower sections, especially during the warmer months when the current is gentler. Its clear waters and proximity to scenic areas make it a great destination for outdoor enthusiasts looking to explore the region. However, swimmers should be aware of the river's fluctuating conditions and be prepared for its chilly waters.
