Best Time to Visit South Korea: Month-by-Month Guide

South Korea has four sharply defined seasons, far more distinct than anywhere in Southeast Asia: blossom-filled springs, hot and rainy summers, crisp golden autumns and genuinely cold winters. Picking the right month makes the difference between strolling palace courtyards in perfect weather and dodging monsoon downpours or icy wind. Here is when to visit South Korea, month by month, with notes for Seoul, Gyeongju, Busan and Jeju Island.

The short answer

The best times to visit South Korea are spring, from early April through May, and autumn, from late September to early November. Cherry blossoms usually peak in Seoul in the first half of April, and fall foliage reaches the mountains in mid-October and the cities from late October into early November. If you can, avoid the summer rainy season, called jangma, from late June through July, and the deep cold of January.

Spring: cherry blossoms and lanterns

Cherry blossoms move up the peninsula from south to north. They usually open on Jeju and along the south coast in late March, reach Busan and Gyeongju around the start of April and arrive in Seoul in the first half of the month. In Gyeongju, the lanes around Bomun Lake and the royal burial mounds turn pink and white; in Seoul, locals picnic in the parks along the Han River and in the palace gardens. May brings azaleas and, around Buddha’s Birthday, temples hung with thousands of colorful lanterns. The one drawback of spring is the occasional hazy day caused by fine dust, so check the air-quality forecast and pack a mask.

Summer: jangma, heat and typhoons

Jangma, Korea’s rainy season, typically runs from late June to late July, with intense showers between muggy, overcast days. In August the humid heat often tops 86°F (30°C), and from August into September typhoons can hit Jeju and the south coast, sometimes pausing flights and ferries for a day or two. Summer still has its rewards: deep green mountains, lively beaches in Busan and long evenings in the city. If you travel then, leave a buffer day before your flight home and save museums and covered markets for the afternoons.

Autumn: the most beautiful season

From late September to early November the skies are clear, the air is dry and the temperatures are ideal for walking. Foliage starts in the northeastern mountains: Seoraksan National Park usually turns red and gold around mid-October, while Seoul, Gyeongju and the royal palaces are at their best from late October into early November. It is also festival season. Keep an eye on Chuseok, the harvest holiday that falls in September or October depending on the lunar calendar: for about three days much of the country travels home, transport is packed and some shops and restaurants close.

Winter: dry cold and snow

From December to February Seoul is cold, with lows often well below freezing and a biting wind; the mountains of Gangwon Province get snow and ski resorts open. In return you get crystal-clear skies, uncrowded palaces and lower hotel rates. Warming up on heated ondol floors in a traditional guesthouse, or over a bowl of hot stew, is part of the experience. Jeju stays milder than the mainland. Lunar New Year, called Seollal, is another week of heavy domestic travel.

Which season suits you

• First-time visitors and couples: mid-April to May, or mid-October to early November.
• Families with teens: May, with long mild days, or the summer holidays if you base yourselves on the coast.
• Nature lovers: October for foliage in Seoraksan, May for hiking.
• Combining Korea with Vietnam: a Korean autumn pairs well with northern Vietnam, which is cool and clear in October and November, and a Korean spring pairs well with central and southern Vietnam.
