May is called the queen of the seasons.
Today (the 2nd), the first Monday in May, the sky will be clear without worrying about dust, but there is still a chill in the morning and evening.
Currently, the temperature in Seoul is 10.3 degrees Celsius, which is below the normal level, and there may be some places where there is frost in the mountainous areas of Gangwon, where the temperature is low.
In the daytime, the temperature will rise by more than 10 degrees compared to the morning due to the sunlight, so you should dress well for the large daily temperature difference.
Although the temperature rises significantly during the day, the atmosphere is still unstable as cold air still resides above Korea.
It will be raining all over the east from around the time you get home from work to the evening. The amount of rain will be small, but it will fall loudly with thunder and lightning.
There will be thick fog throughout the central inland until morning, and the wind will be calm today.
The temperature will rise more and more.
