During the day, the sun raises the temperature quickly, but on sunny days like this, radiative cooling is more active, and the temperature quickly drops again after the sun goes down.
Tomorrow (the 3rd) too, with the sunny spring weather continuing, the daily temperature difference will be very wide.
There are places where the daily temperature difference is as big as 20 degrees or so, as if you go back and forth between two seasons in one day.
Tomorrow, the air quality will be normal nationwide.
However, in Incheon, southern Gyeonggi, and Chungnam, the air may be temporarily cloudy at night.
If you look at the temperature tomorrow, the daytime temperature in Seoul will be 16 degrees and Daejeon 17 degrees, slightly higher than today, and the southern provinces will also rise significantly to Gwangju and Daegu 18 degrees.
The weather will be mostly sunny until next Wednesday, but the temperature will drop temporarily after rain in central and Honam on Thursday morning.
