According to the Korea Meteorological Administration on the 11th, the expected daytime high temperatures for the next day range from 25 to 34 degrees Celsius. Most regions will experience daytime temperatures above 30 degrees, with some inland areas of Gyeongsang Province expected to exceed 33 degrees. In some inland areas such as Daegu and Yongin in Gyeonggi Province, the perceived temperature will be above 33 degrees. The lowest temperatures in the morning are expected to be between 16 and 25 degrees Celsius.

The expected minimum and maximum temperatures in major cities are Seoul 20°C and 30°C, Incheon 19°C and 25°C, Daejeon 18°C and 32°C, Gwangju and Ulsan 20°C and 32°C, Daegu 21°C and 34°C, and Busan 20°C and 29°C.

In the southeastern inland areas of Jeonbuk, eastern inland areas of Jeonnam, southwestern inland areas of Gyeongbuk, and western inland areas of Gyeongnam, showers of around 5mm may occur late in the afternoon the next day, but they will be insufficient to cool down the heat. The showers are analyzed to occur due to unstable atmosphere caused by the heating of the lower air layer by sunlight.

Ozone concentrations are high nationwide except for Jeju. The ozone levels in Seoul, Gyeonggi, Jeonnam, and Gyeongnam regions are at a 'very bad' level.

Sea fog may form over the ocean. It is analyzed that the hot southwest winds, a factor of the heat, pass over the relatively cold sea, causing fog to form. On the west coast, southern coast of Jeonnam, and southern coast of Gyeongnam, fog is expected to flow in from the sea from tonight until tomorrow morning, reducing visibility to less than 200 meters.
