When is the best time to visit Seoul?

The best time to visit Seoul is between April and June, the most comfortable stretch of the year on these averages.

Seoul has a real winter and a real summer. Snow is part of the cold months, not a freak event. The outdoor year is short in the middle and long at the ends of summer. Seoul is a city in South Korea. This page is about Seoul, not a country average.

Most visitors come once the freeze has lifted, or they come on purpose for the cold. Do not book Seoul as a sunlounger destination. The monthly table owns the averages. This layer is the year those numbers sit inside.
