Rain expected in Jeju, southern and eastern coasts; temperatures normal

South Korea is bracing for a day of mixed weather on Wednesday, June 24th, with rain expected in several key regions. The Meteorological Administration forecasts scattered clouds for the central areas, while the southern regions and Jeju Island will experience generally overcast conditions.

Jeju Island is set to receive the brunt of the rainfall, with precipitation continuing throughout the day. The southern coast, including parts of Jeonnam and Gyeongnam, will also see rain, particularly from early morning. The East Coast, specifically southern Gangwon and Gyeongbuk, can expect rain from the morning, though it is forecast to cease in the southern Jeonnam and western Gyeongnam inland areas by nightfall.

Strong winds are a significant concern for Jeju Island, with a wind advisory in effect. Gusts could reach over 70 km/h, with mountainous areas experiencing even higher speeds up to 90 km/h. Coastal areas of Jeonnam and Gyeongnam will also face strong winds until the morning.

Maritime warnings are in place for the seas south of the West Sea, the South Sea, and Jeju waters, where winds are expected to be very strong, accompanied by high waves. The East Sea will also experience strong winds and rough seas. Swells will affect the East Coast from Tuesday and reach Jeju's coast by Wednesday afternoon, prompting warnings for people to stay away from coastal areas due to the risk of large waves crashing onto beaches and over structures.

Despite the weather, temperatures are expected to be in line with seasonal averages, with morning lows ranging from 14 to 20 degrees Celsius and daytime highs reaching 22 to 30 degrees Celsius. Air quality is predicted to be good across the country, with the exception of Incheon, where ozone levels are expected to be 'bad'.
