Best Time to Visit South Korea
The best time to visit South Korea is generally April–June & September–November. This season-by-season guide covers peak, shoulder and low season, the weather you can expect, the festivals that fill hotels and what to pack.
Weather in South Korea
Four clear seasons: mild blossom-filled spring, a humid summer monsoon in July, crisp clear autumn, and a cold dry winter with ski conditions inland.
Peak, shoulder and low season
Peak season runs April (blossom) and October (autumn colour), with the highest flight and hotel demand. Shoulder season (May–June and September) offers similar conditions with thinner crowds. Low season (December–February) is the cheapest, with less predictable weather or reduced opening hours at some attractions.
Festivals and holidays
Chuseok (autumn) and Lunar New Year are the busiest domestic travel periods, when many businesses close.
What to pack for South Korea
Comfortable walking shoes, a rain layer for July, and a warm coat in winter.
