December in Jeju, the southernmost island of Korea, presents a unique blend of mild winter conditions distinct from the mainland. Temperatures typically hover between 5C and 10C (41F and 50F), offering a more temperate climate. Rainfall is relatively low, and while snowfall is possible, it is typically light and infrequent. This creates a landscape where the island’s volcanic features and lush evergreen vegetation stand in contrast to the dormant winter scenery common in other parts of Korea.
The island’s moderate December climate offers several advantages. Outdoor activities, such as hiking the iconic Hallasan Mountain or exploring the volcanic coastline, remain feasible. Jeju’s famed citrus fruits, including tangerines and oranges, are in their prime harvest season, providing a vibrant local flavor. The relatively lower tourist volume compared to peak seasons allows for a more tranquil experience. Historically, Jeju’s unique geographical location has resulted in a distinct culture influenced by its milder climate, evident in its traditional architecture and agricultural practices.
