It is expected that most regions across the country will continue to experience a heat wave until this weekend. The perceived temperature will soar above 36 degrees. However, starting early next week, temperatures are expected to drop slightly, bringing a temporary pause to the heat.
According to the Korea Meteorological Administration on the 11th, the maximum daytime temperature in Seoul is expected to rise to 36 degrees on Saturday, the 12th, and to 34 degrees in Incheon and Daejeon, and 34 degrees in Gwangju, 31 degrees in Daegu, and around 31 degrees in Busan and Ulsan. The minimum morning temperatures across the country are forecasted to be between 19 and 25 degrees.
This heat wave is attributed to the Tibetan high-pressure system and the North Pacific high-pressure system covering the Korean Peninsula. However, from Sunday onwards, cracks in this pressure system are expected to cause the minimum temperature on Monday morning, the 14th, to drop to between 21 and 24 degrees and the maximum daytime temperature to decrease to between 26 and 33 degrees. However, the perceived temperature is likely to remain high due to high humidity.
The weather is generally expected to be sunny across the country, although there may be occasional clouds in the Yeongdong region of Gangwon and southern areas. The concentration of fine dust is expected to be at a 'good' level nationwide.
Jeju Island is expected to be cloudy until the 13th, with rainfall expected in various places, ranging from 10 to 60 mm, possibly exceeding 80 mm. This is due to the influence of a pressure trough passing over the southern seas and the moisture being drawn in along the edge of the high pressure. In the Jeonnam region, rain is expected to begin from early on the 13th, while in the southern part of Jeonbuk and Gyeongnam, rain is expected to start in the morning, with precipitation estimated at 5 to 50 mm (5 to 20 mm in the southern part of Jeonbuk). Showers may occur in the northwest part of Jeonnam from late afternoon on the 12th.
At sea, there may be strong winds and thunder and lightning, particularly in the southern waters off Jeju Island, so caution is advised for navigation and fishing activities. Wave heights are expected to be between 0.5 and 2.0 meters in the open waters of the East, West, and South Seas, with heights reaching a maximum of 3.5 meters in the inner offshore areas.
The Korea Meteorological Administration advised, "For the time being, with high temperatures and humid weather expected to continue, it is necessary to ensure adequate hydration and rest during outdoor activities."
