Best Time to Visit Korea

Spring (March–May)

Spring is one of Korea’s two prime seasons. Cherry blossoms typically peak in early April in Seoul, late March in Busan, and mid-April in mountain areas.

• Temperatures: 5–20°C, warming quickly
• Yellow dust (hwangsa) from China is occasional in March; check air quality apps
• Cherry blossom peak hotspots: Yeouido in Seoul, Jinhae festival, Gyeongju’s tomb park
• Outdoor festivals begin in April

Late May into early June is mild, green, and one of the most pleasant times before summer heat sets in.

Summer (June–August)

Hot and humid, with monsoon rains in late June through mid-July. Temperatures regularly hit 30–35°C with high humidity.

• Beaches (Haeundae, Gwangalli) officially open July–August
• Mountain valleys and Jeju are popular escapes
• Many indoor venues run aggressive AC — bring a light layer
• Festivals: Boryeong Mud Festival (July), Busan International Film Festival (October starts planning here)

If you visit in summer, plan major outdoor walks for early morning or evening.

Autumn (September–November)

Korea’s second prime season — and arguably its best. Cool, dry, and clear skies.

• Temperatures: 10–25°C, falling steadily
• Foliage peak: late October in mountains, early-to-mid November in Seoul
• Best for walking: ideal weather, no rain, photogenic light
• Festivals: Andong Mask Festival, Jinju Lantern Festival, Seoul Lantern Festival

If you can only visit once, October is the safest bet.

Winter (December–February)

Cold and dry. Snow occurs but isn’t heavy in most cities — more common in mountain areas.

• Temperatures: -5 to 5°C, occasionally dropping to -15°C
• Ski season opens early December at Yongpyong, Vivaldi Park, High1
• Indoor culture is rich: jjimjilbang saunas, hot stew season, K-drama winter scenes
• January is the coldest month; Lunar New Year (Seollal) closes many shops for 3 days

Winter has its own beauty — palaces in snow are striking — but bundle up seriously. Korean winter is colder than European or US East Coast winters at the same latitude.

What to pack

• Spring/fall: layers; a light jacket, t-shirt under
• Summer: light breathable clothes, umbrella for monsoon, sunscreen
• Winter: serious coat, gloves, hat, hand warmers; thermal layers

Avoid these dates if possible

• Chuseok (Korean Thanksgiving, mid-Sep to early-Oct): massive domestic travel, shops close
• Seollal (Lunar New Year, late Jan to mid-Feb): same as above
• Suneung (College Entrance Exam, mid-November): subways run early, airplanes ground briefly during English listening test
