The four seasons at a glance
- Spring (March–May): mild and changeable, with cherry blossoms. Yellow dust from the west and fine dust days are common — check the air quality.
- Summer (June–August): hot and humid. The monsoon (jangma) brings heavy rain from late June into July, and typhoons can come in late summer.
- Autumn (September–November): clear, dry and comfortable — many people’s favourite time to visit, with autumn leaves. Typhoons are still possible early in the season.
- Winter (December–February): cold, dry and windy in Seoul; wind chill makes it feel colder than the forecast. Busan and Jeju are milder.

Indoor heating and air conditioning
Homes and many guesthouses use floor heating (ondol), and the subway, shops and cafés are kept warm in winter — wear layers you can take off. In summer the air conditioning is strong, so bring a light layer for long subway or bus rides.
Rainy or very cold day? Plan museums, markets and indoor attractions.
