On the way to work today (15th), you should come out with your collar firmly up.
There are many places with the lowest temperatures this fall. Currently, the temperatures in Cheorwon and Gimhwa have dropped to -2.7 degrees Celsius, while in Seoul it has dropped to 6.8 degrees, and the temperature has dropped by about 5 degrees as of 6 o'clock yesterday morning.
As the wind blows here, the perceived temperature will be lower.
As the temperature drops so sharply, there may be places where frost or ice freezes in inland and mountainous areas.
Even during the day, the temperature may not increase significantly, but there are places where the daily temperature difference between day and night is wider than 15 degrees, so you should take good care of your health.
A clear sky will open today.
There is a place on the east coast where swelling waves come in strongly, so you should refrain from approaching the coast.
The highest temperature in the daytime will be 18 degrees in Seoul and 20 degrees in Daegu.
For the time being, this chilly weather will continue.
