One of the first questions most people ask when planning a trip to South Korea is when is the best time to visit? There is no simple answer as it depends on your particular interests. Also, many people are constrained to visit at specific times such as school holiday periods which limits your options. If you are more flexible you can seek out a great airfare deal in a non peak time.
Other people visit South Korea with an intent to attend a specific event such as a festival or K-Pop event, so it is worthwhile to do your homework on these activities before you book your flights.
In general, the best time to go to South Korea is between March and May in the Spring and between September to November in the Autumn/Fall, as these periods are usually sunny, warm and dry. If you love skiing then make sure you check out the options over Winter. And while hot and humid, there are many great festivals to experience in Summer.

Spring in South Korea – March, April and May
Spring in South Korea is one of the most popular times to visit.
- March – The weather is warming up from the very cold winter and the mountains are open for visitors. The weather regularly swings between very cold and warm.
- April – The Cherry Blossom season over the first half of April is a wonderful time to visit South Korea, with great viewing options across South Korea, as the blooms sweep from south to north. Be aware that April is also the time when yellow dust from the Gobi Desert can cover the country causing increased air pollution – so not a good time to visit for people with allergies.
