Water Temperature in Great Falls: General Trends and Swimming Opportunities
In Great Falls, Montana, the Missouri River runs through the city, providing stunning landscapes and recreational opportunities. However, the water temperature of the river can be quite cold, particularly in the spring and early summer months. During this time, the water temperature typically ranges from 40°F to 55°F (4°C to 13°C), making swimming in the river uncomfortable and potentially dangerous due to the cold, fast-moving currents. The presence of rocks, debris, and strong undertows also makes the Missouri River less ideal for casual swimming.
In the summer, the water temperature in the Missouri River can rise slightly, reaching more tolerable levels of around 60°F to 70°F (15°C to 21°C), especially in the calmer sections. While these temperatures might be acceptable for brief wading or cooling off, the river's strong current still presents challenges for swimming. Many locals and visitors prefer other water-based activities such as fishing, kayaking, and boating, which allow for more control and enjoyment in the river's waters.
For those looking for a safer, more comfortable swimming experience, Great Falls offers several public swimming pools and nearby lakes. These areas provide warm, controlled environments ideal for swimming, with temperatures typically around 78°F to 82°F (26°C to 28°C).
