On Thursday the 20th, the daytime high temperature in Seoul will rise to 35 degrees Celsius, continuing the 'scorching heatwave.' In the southern regions, rain or thick clouds will cause daytime temperatures to drop by about 2 to 6 degrees compared to the previous day.

According to the Korea Meteorological Administration on the 19th, the morning low temperatures on the 20th are forecasted to be between 17 and 24 degrees Celsius depending on the region, with daytime highs ranging from 24 to 35 degrees. Heatwave warnings are in effect for most areas nationwide, with the highest perceived temperatures expected to be around 33 degrees, so the Meteorological Administration advised referring to heatwave impact forecasts and taking precautions to prevent heat-related illnesses.
