What to wear to Korea in April?
First of all, the climate of Seoul is the closest to that of Qingdao, China, because the two cities are almost at the same latitude, and both are near the sea, with similar climate. The weather in Seoul began to get hot in April, from about MINUS 10 degrees in early April to more than 20 degrees above zero at the end of April. In this case, you can decide the clothes you need to bring according to the specific time to go to Korea. Wear a thinner coat, short-sleeved T-shirt or something, and just wear a thinner pair of jeans underneath.
The climate temperature of Jeju Island is similar to that of China and Shanghai. The temperature in March and April is generally around 16 degrees. But Jeju Island is surrounded by the sea, so it is windy. Going to the seaside to see the scenic spots during the day is still a little cold in the morning and evening. It is recommended to bring a windbreaker or coat. The Cherry Blossom Festival in Jeju Island opened in March, and the Rape Flower Festival in Jeju Island opened in April. Spring is best for Jeju Island.
