As severe heat waves continued primarily in areas west of the Taebaek Mountains on the 6th, heat advisories will remain in effect for some parts of Yeongseo, Gangwon Province, as well as broader areas including Seoul and Incheon on the 7th, which marks the seasonal turning point of Ipchu (beginning of autumn). Over the weekend, rain is expected due to the indirect influence of Typhoon Dolphin, the 13th typhoon of the season, and changes in the North Pacific High.

■ Heat Wave Conditions on the 6th... Yongsan-gu, Seoul 39.9°C, Jongno-gu 37.9°C On the 6th, severe heat exceeding 39°C was observed primarily in areas west of the Taebaek Mountains. An Automatic Weather Station (AWS) in Yeongdeungpo-gu, Seoul, recorded 40.0°C at around 1:57 p.m., but this equipment is installed on the rooftop of an elementary school and is not used for heat wave and tropical night advisories due to observation environment issues. Meanwhile, in Yongsan-gu, Seoul, which has a relatively good observation environment, the temperature climbed to 39.9°C at 5:15 p.m. The Seoul Weather Station in Jongno-gu, the representative observation point for Seoul, recorded 37.9°C, marking the fifth-highest temperature since observations began in August 1908. Outside Seoul, Geumsa-myeon in Yeoju, Gyeonggi Province, recorded 39.1°C, Gumi in North Gyeongsang Province 38.2°C, Namwon in North Jeolla Province 37.9°C, and Baengnyeongdo in Ongjin-gun, Incheon, 32.8°C, each marking the second-highest temperatures since observations began at their respective locations.

■ Heat Wave Continues on Ipchu, the 7th... Seoul Forecast at 39°C, Incheon at 38°C On the 7th, which marks the seasonal beginning of autumn (Ipchu), heat wave warnings and advisories will continue in some parts of Yeongseo, Gangwon Province, including Chuncheon and Hoengseong, as well as in Seoul, Incheon, southern Gyeonggi Province, Jeonju in North Jeolla Province, eastern Gwangju, and Gwangyang in South Jeolla Province. Morning low temperatures are forecast at 22–27°C, and daytime highs at 31–39°C. Daytime high temperatures by major cities are expected to reach 39°C in Seoul, 38°C in Incheon and Gwangju, 37°C in Daejeon and Daegu, 35°C in Busan, and 34°C in Ulsan. Due to strong sunlight, ozone levels in the afternoon are expected to reach 'very bad' in Seoul, Incheon, and southern Gyeonggi Province, and 'bad' in northern Gyeonggi Province and South Chungcheong Province.

■ Rain and Waves Warning for the Weekend... Impact of Typhoon Dolphin From the early morning of the 8th through the 9th, heavy rainfall exceeding 120 mm is forecast for the Gangwon East Coast and mountainous areas. During this period, in addition to Gangwon, 20–60 mm of rain is expected on the northern East Coast of North Gyeongsang Province and in northeastern mountainous areas, 5–40 mm on the southern East Coast of North Gyeongsang Province, and 5–30 mm in mountainous and mid-mountainous areas of Jeju. Due to the influence of Typhoon Dolphin, strong winds and high waves are expected in the far southern seas off Jeju and the outer far seas of the eastern South Sea. Swells are also forecast to successively roll into the Jeju coast, the southern coast of South Jeolla Province, the East Coast, and the southern coast of South Gyeongsang Province. In particular, starting from the 8th, high waves along the East Coast may overflow coastal rocks, breakwaters, and coastal roads, requiring special caution when approaching these areas.

■ Heat Wave Gradually Easing... "Caution Advised for Outdoor Activities During the Day" As the weekend approaches, changes are expected in the influence of the North Pacific High and the Tibetan High. As a result, clouds are expected to flow into the upper atmosphere, and relatively cool northeast winds will blow in, reducing solar radiation. On the 8th, morning lows are forecast at 22–27°C and daytime highs at 27–36°C, while on the 9th, morning temperatures of 21–26°C and daytime highs of 26–35°C are expected. Although the heat wave will persist through the 7th, temperatures are expected to gradually drop thereafter. However, since the heat is not expected to fully subside, continued caution is necessary for outdoor activities during the day, even if temperatures drop slightly.
