South Korea weather & when to go: September
September sees the start of autumn in South Korea, although at the beginning of the month, expect the heavy rain and muggy heat of the previous months to continue. Travel later in the month for more favourable weather conditions.
September's weather in detail
September sees the muggy heat and heavy rain of the previous summer months begin to dwindle. As the month progresses, the heat begins to drop and the rains lessen, thanks to autumn gradually taking hold. This is when South Korea bursts into colour with stunning shades of orange and red peppering its landscapes.
For most of the month, however, temperatures remain high, nudging towards a maximum of 30°C, and humidity levels can make things feel a bit sticky and uncomfortable.
The breezy coastal resorts around Busan offer a refreshing respite, as do the mountainous National Parks, such as Seoraksan. Time your visit towards the end of September for fewer wet days and a much more comfortable climate.
