It was sunny at the beginning of the holiday, but tomorrow (the 21st) has a rain forecast for the whole country.
At dawn, rain will spread across the country one after the other from the west, which can be very strongly concentrated.
In particular, it is expected that over 100mm will pour in the southern coast and Jeju Island, where moisture flows in, and 20~70mm in other areas.
However, from the afternoon, the days will gradually clear and the clouds will clear in the evening for a while, so you can see the full moon rising through the clouds.
Tomorrow morning Seoul will start at 21 degrees, and the daytime maximum temperature will be 26 degrees.
The day after tomorrow, rain forecasts are included in many parts of the country, so you should refer to the weather on the way back.
