Water Temperature in Idaho Falls: General Trends and Swimming Opportunities

The Snake River, which flows through Idaho Falls, offers scenic views and various recreational activities, but it’s not widely known for swimming due to its cold water temperatures and strong currents. During the warmer months, typically from late spring to early fall, the river's water temperature can range from 50°F to 65°F (10°C to 18°C), making it quite chilly for most swimmers. These cold temperatures can be refreshing in hot weather but are often too cold for extended swimming.

While swimming in the Snake River is not as popular as other water sports, activities like kayaking, rafting, and fishing are common in this area. The river's strong currents, especially near the falls, also pose safety risks, making swimming less ideal. For those determined to take a dip, it's important to exercise caution and be aware of the river's fast-moving waters and potential hazards, including submerged rocks and varying water levels.

For a more comfortable and safer swimming experience, Idaho Falls residents and visitors often opt for nearby lakes, reservoirs, or public pools, where the water is warmer and calmer. Some of these spots can reach temperatures around 70°F to 75°F (21°C to 24°C) in the summer, providing a more inviting environment for swimming.
