According to the Korea Meteorological Administration on the 5th, the minimum temperature the next morning is expected to be between 14 and 21 degrees Celsius, and the maximum temperature during the day will be between 22 and 29 degrees Celsius. Similar to the current day, daytime temperatures will rise to around 30 degrees Celsius mainly along the East Coast and inland areas, resembling early summer weather.

The expected minimum and maximum temperatures in major cities are Seoul 17°C and 26°C, Incheon 16°C and 22°C, Daejeon 16°C and 28°C, Gwangju 17°C and 27°C, Daegu 17°C and 28°C, Ulsan 17°C and 24°C, and Busan 18°C and 23°C.

However, there will also be showers and ozone. Showers of 5 to 40 mm are forecast in parts of northern Gyeonggi, Gangwon, and eastern Gyeongbuk in the afternoon of the next day. This is due to unstable atmospheric conditions caused by the heating of air near the ground by daytime sunlight. Ozone levels are at a 'bad' level in Gyeonggi, Yeongseo region of Gangwon, Sejong, Chungbuk, Chungnam, Jeonbuk, Daegu, Gyeongbuk, and Gyeongnam, while other regions are at a 'moderate' level.

The sky is expected to be partly cloudy the next day. Jeju, Jeonnam, and Gyeongnam will be cloudy in the morning but gradually clear up in the afternoon. Due to a pressure trough passing south of Jeju, rain falling on Jeju will continue until the next morning before stopping.

Dense fog will form along the central west coast. From the night of the current day until the next morning, sea fog from the West Sea will move inland, reducing visibility to less than 200 meters. Fog reducing visibility to less than 1 kilometer is also expected in other areas. Sea fog will also persist over the Jeju sea until the next day.
