Water Temperature in Missoula: General Trends and Swimming Opportunities

In Missoula, Montana, the Clark Fork River is a popular waterway that runs through the heart of the city. During the summer months, the river's water temperature generally ranges from 50°F to 65°F (10°C to 18°C). While these temperatures can be refreshing on a hot day, they are still relatively cold for swimming, which can make prolonged immersion uncomfortable for some people. The current in certain areas of the river can also be strong, adding an element of caution for those attempting to swim or wade.

Swimming opportunities in the Clark Fork River are somewhat limited due to the river's cold temperatures and sometimes fast-moving waters, especially in the spring when snowmelt raises the flow. However, there are calmer sections of the river that may be more suitable for wading or short, cool dips, particularly in the late summer when the water has warmed slightly. In general, swimmers should be prepared for brisk, invigorating water and should always be mindful of the river's flow and any potential hazards beneath the surface.

The Clark Fork River is more commonly enjoyed for activities such as kayaking, canoeing, and tubing, which are better suited to the water's temperature and current conditions. For those who prefer warmer water for swimming, nearby lakes such as Seeley Lake or Flathead Lake provide more comfortable temperatures for a full day of aquatic fun. Despite the chilly temperatures, the Clark Fork remains a scenic and popular spot for locals and visitors to engage in various outdoor activities, including water sports and relaxing by the riverbanks.
