September Jeju Travel Guide: Weather, Outfits, and Recommended Attractions

September in Jeju is a transitional period from late summer to early autumn, characterized by pleasant breezes and ideal weather for outdoor activities. Visitors can enjoy iconic autumn landscapes such as pink muhly and silver grass, making it a popular destination, especially during public holidays like Chuseok. While daytime temperatures can be warm, evenings are cool, ensuring a comfortable travel experience.

For September Jeju trips, Yongnuni Oreum offers views of the autumn sky and silver grass, while Sangumburi features vast silver grass fields. Eastern Jeju highlights include Boromwat, where buckwheat and celosia flowers are in full bloom, the lush trails of Secret Forest, Seopjikoji with its ocean views and Seongsan Ilchulbong, and Udo for a leisurely escape. In Seogwipo, the Little Prince Tangerine Farm, which starts early-ripening tangerine picking from September 22, provides a unique experience.

Bloggers suggest packing short-sleeved shirts along with a light jacket or windbreaker to counter Jeju's strong winds in September. The Little Prince Tangerine Farm, in particular, is highly rated by families for its tangerine picking experience, cafe, animal feeding, and photo zones. Its Jeju-esque ambiance and spacious outdoor areas are frequently praised for providing a relaxing visit.
