Spring (March–May)
Mild and increasingly dry, spring is prime season. Cherry blossoms sweep north from the south — typically late March in Jeju and Busan, early-to-mid April in Seoul — lasting only a week or two, so timing matters. Days are pleasant for palaces, hikes, and festivals, though the most famous blossom spots get very crowded. Late spring can bring occasional yellow-dust/fine-dust days.
Summer (June–August)
Hot and humid. The monsoon ("jangma") brings heavy rain from late June into July, and typhoons are possible through September. It's still a lively time for beaches (Haeundae in Busan), water festivals (like Boryeong Mud Festival), and air-conditioned city sightseeing — just pack light, breathable clothes, an umbrella, and sunscreen.
Autumn (September–November)
For many travelers, autumn is the single best season: clear, comfortable days and spectacular foliage. Colours peak in the mountains first and reach the cities roughly late October to mid-November — striking at palaces, temples, and parks like Naejangsan. Weather is stable and great for walking.
Winter (December–February)
Cold and dry, often below freezing, with periodic snow. Winter rewards visitors with skiing and snow resorts in Gangwon, snow-dusted palaces, bright winter-light photography, illuminations, and noticeably thinner crowds. Dress in warm layers and plan indoor breaks (museums, cafés, jjimjilbang saunas).
