This summer's monsoon season is expected to conclude early next week.


According to the Korea Meteorological Administration (KMA) on July 22, "Following Jeju, the monsoon will end in the central and southern regions early next week, marking the start of a significant heat wave. However, localized heavy rainfall may continue due to the influence of the North Pacific High, so caution is advised."


The KMA added that it has determined the monsoon in Jeju ended on July 19 as the North Pacific High expanded into the area.


It was also reported that the monsoon in the central and southern regions is expected to conclude around Monday, July 27.


However, rain is forecast for the capital region and Gangwon from July 24 to 25 due to a stationary front, with showers expected in areas south of Chungcheong. On July 26, the stationary front is anticipated to shift slightly south, bringing rain to the central region, North Jeolla, and North Gyeongsang.


Expected precipitation on July 24 is 30 to 80 mm in the five western islands, 20 to 60 mm in the capital region, inland Gangwon, and mountainous areas of Gangwon, and 5 to 30 mm along the eastern coast of Gangwon. Showers are expected to bring 5 to 40 mm of rain (5 to 30 mm in Gwangju and South Jeolla).


On July 25, rain or showers from the stationary front are expected to total around 5 to 40 mm.


Once the monsoon ends, a prolonged heat wave is anticipated.


By late next week, the North Pacific High in the lower atmosphere, combined with the Tibetan High in the upper atmosphere, is expected to cover the country, leading to extreme heat.


From July 27 to August 2, morning temperatures are expected to range from 23 to 26 degrees Celsius, while daytime temperatures could reach between 29 and 37 degrees, similar to or slightly higher than the average (minimum 22 to 25 degrees; maximum 29 to 33 degrees).
