Goyang sits in South Korea’s greater Seoul capital region along the Han River basin, where the summer monsoon front known as jangma brings weeks of sustained rain from late June through July, followed by a secondary risk from typhoon remnants reaching the peninsula in August and September.
Northwest of Seoul near the Han River’s lower reaches, the city’s low-lying areas are sensitive to the river’s level during heavy rain. Because the jangma front can stall for days over the same area, cumulative rainfall rather than any single storm is often the bigger flood driver, and radar is used alongside river-gauge data on the Han River system to track conditions in real time. The Korea Meteorological Administration operates the national weather radar network. Learn more: Flash Flood Warning Signs on Radar · Open the full Rain Map
