The Cedar River in Washington State is a vital waterway known for its picturesque surroundings and ecological importance. The river’s water temperature is influenced by the season and its mountainous origin, with summer temperatures typically ranging from 55°F to 65°F (13°C to 18°C). In cooler months, the water temperature can drop significantly, often falling below 50°F (10°C), especially in spring when snowmelt contributes to its flow.
Swimming in the Cedar River is possible in certain areas, but it requires caution. The water is often chilly, even in summer, which can be refreshing but challenging for extended swimming sessions. Popular spots for wading or taking a quick dip include calmer stretches near parks or designated access points, such as areas around Renton or along the Cedar River Trail. However, the river’s flow can be swift in certain sections, and swimmers should be mindful of currents and uneven riverbeds.
For a safer swimming experience, visitors may prefer nearby lakes, such as Lake Washington or Lake Wilderness, which offer warmer and calmer waters. The Cedar River remains a popular destination for kayaking, fishing, and enjoying the natural beauty of the Pacific Northwest, even if swimming is not its primary attraction.
