Seoul
Seoul's humid subtropical climate has four distinct seasons, and there is no official “off season.” Some say that the city is at its best in the spring when cherry blossoms bloom, while others prefer fall, when leaves turn into a fiery mass of red, gold, and brown. Winters can be brutal, but they lend the capital city a whitewashed beauty. Summer temperatures often rise into the 90s, with rain falling during the late-summer typhoon period. No matter when you visit, however, there’s plenty to do both indoors and out.
