The Spokane River, which flows through the city of Spokane in Washington state, is a popular river for outdoor recreation. The water temperature in the Spokane River tends to be on the cooler side, particularly because it originates from the higher elevations of the mountains and is fed by snowmelt. During the warmer summer months, typically from June to August, the river temperature ranges from 50°F to 65°F (10°C to 18°C), which can feel quite refreshing, especially on hot days. However, these cooler temperatures may not be comfortable for everyone to swim in for extended periods, although some people still enjoy taking a quick dip.

In the spring, as the snow melts and flows into the river, the water temperature can remain quite cold, dipping below 50°F (10°C). The river also experiences strong currents, particularly in areas where water is funneled through narrower sections or near dams, making swimming in those areas more dangerous. The water can be unpredictable, especially after heavy rainfall, which can cause sudden increases in flow rate and water levels.

Although the Spokane River is not typically known for its swimming opportunities due to the cold water and fast currents, there are designated areas in and around Spokane where swimming and water activities can be enjoyed safely. Some areas of the river, especially near the city’s parks, provide calmer sections that are better suited for water activities like kayaking and tubing. For those looking to swim, local swimming pools or lakes in the surrounding area may offer a safer and more comfortable alternative.
