What is the weather like in Korea? What should I pay attention to?

The climate and marine characteristics of Korea are distinct in four seasons, with hot and humid summer, cool autumn and cold and dry winter. The temperature in Seoul and Beijing is not much different. Busan and Jeju Island are 2~3C higher than Seoul. Jeju Island is near the sea, and the climate is changeable. Visitors had better bring their own rain gear. /zd/ym
