Data: Seoul Open Data, “Han River and major tributary water-quality measurements” (Korea Open Government License Type 1). Hourly observations are provisional; fallback readings are labelled as last checked.

Temperature alone does not make swimming or entering the water safe. Follow designated-facility rules and on-site restrictions.
