Korea is a year-round destination, but each season offers something completely different. The best time to visit depends on what you're looking for.
Spring (March – May) ★ Most Popular
Spring is arguably the best time to visit Korea. Temperatures are mild (10–20°C), and cherry blossoms blanket parks and riverside paths across the country from late March to mid-April. The Yeouido Cherry Blossom Festival in Seoul draws huge crowds, but smaller spots like Gyeongju and Jinhae are equally stunning and less packed.
- Highlight: Cherry blossoms, mild weather, clear skies
- Watch out for: Yellow dust (황사) from China — bring a mask
- Book early: Hotels fill up fast during blossom season
Summer (June – August)
Hot and humid, with monsoon season (장마) typically running mid-June through late July. After the rains, beaches on the east coast and Jeju Island come alive. Summer festivals are lively — the Boryeong Mud Festival and water parks are popular with both locals and tourists.
- Highlight: Beach season, festivals, Jeju Island
- Watch out for: High humidity, sudden downpours
- Tip: Book east coast accommodation well in advance
Autumn (September – November) ★ Highly Recommended
Many locals consider autumn the best season. Cool, dry weather and spectacular foliage — reds, oranges, and golds across national parks and mountain temples. Seoraksan National Park and Naejangsan are the most famous spots for autumn leaves.
- Highlight: Autumn foliage, temple stays, hiking
- Temperatures: 8–20°C — perfect for walking
- Tip: Visit Gyeongju for both history and autumn colour
Winter (December – February)
Cold and dry, with snowfall in January and February. Seoul's winter markets and light festivals add charm to the city. Ski resorts at Yongpyong and High1 are popular weekend escapes for both locals and international visitors. If you're visiting for the thermal spas (찜질방), this is the season for it.
- Highlight: Ski resorts, winter festivals, hot springs
- Temperatures: -5 to 3°C in Seoul
- Tip: Jeju Island stays warmer than the mainland in winter
