Go to Korea on March 15. How's the weather? What to wear?

Hello, the weather in Korea is still cold, and it will drop below zero at night. I suggest you put on more clothes. You must wear a coat. If it's hot, you can take it off.

I want to know where my dear is going to Korea. Gangwon is very cold. It snows heavily in winter, and March doesn't feel like spring. It's still quite cold. You should put on more clothes. Jeju Island is relatively warm. In Seoul, the highest temperature is about 10 degrees, and it may still drop to about 0 degrees at night.
