The early summer heat will appear across the country on tomorrow (19th), the birthday of Buddha and a holiday.
With strong sunlight during the day, most of the regions will exceed 25 degrees, but this heat will soon slow down again.
The air will cool again as it rains across the country from Thursday to Friday.
This rain will mainly fall on the southern coast and around Jeju Island.
There will be many places with thick fog until tomorrow morning.
Especially in the vicinity of rivers and lakes, including the west coast, the visibility will be greatly reduced to around 100m.
Tomorrow, the sky will be generally clear, and the air in southern Gyeonggi and Chungnam will be cloudy in the morning.
You should be careful because the UV and ozone concentrations are high during the day tomorrow.
The rain will start from Jeju Island in the early morning of Thursday and gradually expand throughout the country during the day, and most will stop during the morning of Friday.
