[Tomorrow's Weather] Early Summer Heat Eases... Rain in Most Regions Until Afternoon

On Thursday, May 15, which is also Teacher's Day, the weather across the country is expected to be mostly cloudy, with rain falling in most regions and the early summer heat easing somewhat.

Rain will begin in the central regions, Jeolla region, and Jeju Island from the early morning, spreading to the western inland of North Gyeongsang and the Gyeongnam region in the morning, and then tapering off in most areas by the afternoon. In the inland areas of North Gyeongsang, there may be places where less than 0.1 mm of raindrops fall between the morning and afternoon.

The expected precipitation is 5 to 30 mm in the Seoul metropolitan area, 5 to 20 mm in the inland and mountainous areas of Gangwon, 5 to 10 mm in the Chungcheong region and Jeju Island, around 5 mm in the eastern coast of Gangwon, Jeolla region, and southern coast of Gyeongnam, and less than 5 mm in Busan, Ulsan, inland Gyeongnam, and western inland North Gyeongsang. In the five West Sea islands, 5 to 20 mm of rain is expected from late night on May 14 for two days.

Morning low temperatures will range from 13 to 19 degrees Celsius, higher than usual for this time of year, while afternoon highs will be between 18 and 25 degrees Celsius, similar to the seasonal average.

Until the morning, sea fog will move in, especially along the west and south coasts, resulting in dense fog with visibility less than 200 meters. Other regions may also experience fog with visibility less than 1 kilometer.

Fine dust concentrations are expected to remain at 'good' to 'moderate' levels nationwide due to the effects of precipitation and smooth atmospheric dispersion.

However, in Seoul, Incheon, and northern Gyeonggi, fine dust may temporarily reach 'bad' levels at night due to air convergence and stagnant atmospheric conditions.

Waves will range from 0.5 to 1.0 meters in the East Sea and South Sea coastal waters, and from 0.5 to 1.5 meters in the West Sea coastal waters.

In the offshore areas (about 200 km from the coastline), wave heights are expected to be 0.5 to 2.0 meters in the East and West Seas, and 0.5 to 1.5 meters in the South Sea.
