Seoul, Gangwon Expect Heavy Rain, Heat Wave

Korea is contending with ongoing monsoon rains across Seoul and Gangwon, with rainfall forecasts ranging from 5 to over 80 millimeters in various areas as a stationary front lingers and then shifts, followed by a sharp rise in heat once the monsoon ends. Forecasts indicate heavy, widespread rain across the central regions and coastal areas on multiple days, with Seoul, Incheon, Gyeonggi, and inland Gangwon often seeing 20–80 mm and higher totals in northern districts, while the east coast and Jeju may receive lighter amounts or showers on certain days. As rainfall subsides, the country is bracing for a severe heatwave, with daytime temperatures approaching or exceeding the upper 30s Celsius and perceived temperatures climbing even higher in humid conditions. The Korea Meteorological Administration has issued unprecedented emergency heatwave warnings, directing the public to reduce outdoor exposure, establish cooling centers, and protect vulnerable groups in heat-prone areas like North Gyeongsang and Pohang. In addition to the heat threat, forecasters warn of tropical nights in parts of the south and Jeju, and advisories for heat waves to remain in effect across multiple regions, alongside coastal and maritime caution for rising waves. Overall, the period promises intense regional rainfall followed by an extreme heat phase, underscoring the volatile and escalating nature of East Asian summer weather.
