Today (the 21st) was a day suitable for short sleeves, as the daytime temperature in Seoul exceeded 27 degrees, marking the highest temperature this spring.
However, the weather will change rapidly tomorrow. Starting tonight in Jeju, rain clouds will blanket the entire country from the early hours until nighttime.
In particular, heavy rain exceeding 80mm is forecasted for the southern coast and Jeju. Other regions will also see significant spring rainfall, ranging from 10 to 60mm. Furthermore, strong winds will gust across the country, with thunder and lightning expected in the southern regions and Jeju.
With the rain, the high temperatures will subside, and Seoul’s daytime temperature will settle at around 18 degrees, approximately 9 degrees lower than today. You might need a spring jacket tomorrow.
Morning temperatures will start slightly higher than today, with Cheongju at 17 degrees and Busan at 15 degrees.
In contrast, daytime temperatures will remain at 19 degrees in Chuncheon and 20 degrees in Daegu.
The rain will stop altogether by tomorrow night, and clear weather will resume the day after tomorrow.
