‘Churaebulsachu’ Autumn Heatwave Continues Through Weekend... Next Week Also Hot

Although Baekro (白露), which marks the beginning of dew on the 8th, has arrived, the nationwide high-pressure system is expected to continue the autumn heatwave through the weekend and next week. Daytime temperatures over the weekend are forecast to approach summer levels of around 30 degrees Celsius, with a large daily temperature range of about 15 degrees.

The highest daytime temperatures on the 8th in major regions are Seoul 31°C, Incheon 28°C, Suwon 30°C, Chuncheon 31°C, Gangneung 28°C, Cheongju 30°C, Daejeon 29°C, Jeonju 30°C, Gwangju 30°C, Daegu 28°C, Busan 28°C, and Jeju 29°C.

According to the Korea Meteorological Administration, the average temperature in Seoul on the 5th was 28.5°C, marking the hottest September day on record. Besides Seoul, tropical nights in September were observed in various parts of the country including Incheon, Cheongju, Gunsan, Yeosu, and Jeju Island. This is the fourth time since meteorological observations began in 1907 that a tropical night has occurred in Seoul during September.

The Korea Meteorological Administration expects the heatwave to continue for the time being. It forecasts that daytime highs will rise to around 30°C in the central regions excluding Gangwon Yeongdong, as well as in Jeolla and western Gyeongsang provinces. Gangwon Yeongdong and eastern Gyeongsang provinces will maintain temperatures between 25°C and 30°C. Weekend morning lows are expected to be between 15°C and 22°C, with daytime highs ranging from 25°C to 31°C.

This weather is due to the east wind blowing along the edge of a high-pressure system located in northeastern China, which heats up as it crosses the Taebaek Mountains. Under the influence of the dry high-pressure system, temperatures will rise during the day due to sunlight and drop at night, resulting in a large daily temperature range until the 10th. Therefore, except for Gangwon Yeongdong on the east side of the Taebaek Mountains, most regions nationwide are expected to experience lingering heat for the time being.

After Monday the 11th, hot and humid air will continue to move up from the south, raising even the lowest temperatures, so the late heatwave is expected to persist for some time. The Korea Meteorological Administration stated, “The central region will enter the edge of the high-pressure system, causing the weather to gradually become cloudy, and morning temperatures will rise again to around 17°C to 23°C.”
