Best Time to Visit
The best time to visit Seoul is during Spring (March to May) or Autumn (September to November). Spring brings cherry blossoms and mild temperatures, while autumn offers spectacular fall colors and comfortable weather conditions.
Spring (March-May) is particularly popular for cherry blossom viewing, with temperatures gradually warming up and relatively low rainfall. The city's parks and streets come alive with beautiful pink and white blossoms.
Summer (June-August) is hot and humid with frequent rainfall, particularly during the monsoon season (late June to July). Despite the weather, this is peak tourist season with many cultural festivals and events.
Autumn (September-November) offers pleasant temperatures and stunning fall foliage. This is an excellent time for outdoor activities and sightseeing, with clear skies and comfortable temperatures.
Winter (December-February) is cold and relatively dry, with occasional snow. While temperatures can drop below freezing, this season offers unique experiences like winter festivals and skiing in nearby mountains.
