Water Temperature in Portland: General Trends and Swimming Opportunities

In Portland, Oregon, the Columbia River flows through the city, offering opportunities for various water activities such as boating, kayaking, and fishing. However, swimming in the Columbia River is generally not recommended due to the river's cold temperatures, fast currents, and the presence of occasional debris. During the summer months, the water temperature typically ranges from 60°F to 70°F (15°C to 21°C), which can be refreshing for brief dips but may be too cold for comfortable, prolonged swimming. In early spring and late fall, the water temperature can drop to 40°F to 50°F (4°C to 10°C), making swimming unsafe and highly uncomfortable.

Despite these chilly temperatures, the Columbia River is popular for recreational boating and other activities, particularly around the areas of Tom McCall Waterfront Park and the area near the Hawthorne Bridge. Swimming is less common, and those who choose to enter the water are typically prepared with wet suits or other gear to protect against the cold. The river’s currents can also be dangerous, so safety is a primary concern for anyone considering swimming.

For those seeking a safer and warmer swimming experience, Portland has a variety of public pools and nearby lakes, like the Columbia Slough, that offer designated swimming areas with controlled conditions. Locations such as the Sellwood Riverfront Park provide opportunities for water recreation in more secure, accessible environments, making them more suitable for swimming compared to the Columbia River itself.
