South Korea has four very clear seasons: cherry blossoms in spring, a hot and rainy summer, spectacular autumn colours and a cold, dry winter. I lived through all of them during my exchange year in Seoul, and the season makes a huge difference to your trip. This guide explains the best time to visit South Korea, month by month, with weather, festivals, holidays to avoid and where to go.
Best Time to Visit Korea: The Short Answer
- Best overall: April to early June and September to November.
- Cherry blossoms: late March in the south (Jinhae), early to mid April in Seoul.
- Autumn leaves: mid to late October in Seoraksan, late October to early November in Seoul.
- Rainy season (jangma): roughly late June to late July.
- Avoid: Seollal (Lunar New Year) and Chuseok (harvest festival), when transport sells out.
Korea Seasons at a Glance
| Season | Months | Weather | Highlights |
|---|---|---|---|
| Spring | April to May | mild, sunny, some yellow dust days | cherry blossoms, festivals, hiking |
| Summer | June to August | hot and humid, monsoon rain | beaches, Busan, night markets, mountains |
| Autumn | September to November | clear skies, cool | autumn leaves, hiking, food |
| Winter | December to February | cold and dry, around minus 2°C in Seoul in January | skiing, winter festivals, hot springs, few crowds |
Spring: Cherry Blossom Season
Cherry blossoms arrive first in the south. Jinhae near Busan usually blooms in late March and hosts the famous Jinhae Gunhangje festival. In Seoul, the blossoms open in early April, with full bloom around the second week of April along Yeouido’s Yeouiseo-ro (often still called Yunjung-ro) and at Seokchon Lake. Spring is busy but beautiful, and May is one of the best months overall. Watch out for occasional fine dust days, when air quality is poor.
Summer: Heat and Jangma
The monsoon season, called jangma, usually brings heavy rain from late June to late July in central Korea, starting a few days earlier in the south and on Jeju. After that, August is hot and humid, with highs around 30°C or more. Typhoons can affect the south in August and September. Summer is the season for Busan beaches, the east coast and cool mountain valleys, and Seoul’s nights by the Han River are lively.
Autumn: The Best Season
Autumn is my favourite time in Korea. September can still be warm, but October and early November bring clear skies, crisp air and red and yellow leaves. Seoraksan National Park peaks around mid to late October, Seoul’s palaces and Bukhansan around late October to early November. Read my Sokcho and Seoraksan guide for the mountains.
Winter: Cold but Clear
Seoul winters are cold and dry, with January averages around minus 2°C and nights often below minus 6°C. Snow is not guaranteed in Seoul, but the mountains in Gangwon have ski resorts. Winter is good value, with fewer tourists, cosy cafés, street food like hotteok and fish-shaped bungeoppang, and sunrise trips to the coast, like Jeongdongjin. My guide to Korea in winter covers the ski resorts, winter food and what to pack.
Korea Month by Month
| Month | Verdict |
|---|---|
| January | very cold, quiet, cheap; Seollal sometimes falls in late January |
| February | cold; Seollal often in February |
| March | spring begins, blossoms in the south at the end |
| April | cherry blossoms in Seoul, excellent but busy |
| May | warm and pleasant, one of the best months |
| June | warm, rainy season starts late in the month |
| July | monsoon rain, humid |
| August | hot, beach season, typhoon risk |
| September | pleasant late in the month; Chuseok often falls here |
| October | clear skies, autumn leaves, excellent |
| November | autumn leaves early, getting cold |
| December | cold, Christmas lights, winter food |
Holidays to Avoid
- Seollal (Lunar New Year): usually late January or February, three days. Trains and buses sell out and many shops close.
- Chuseok (Korean Thanksgiving): usually September or early October, three days. Families travel home and transport is packed.
Plan around these holidays and book KTX trains early. See my guide to getting around South Korea.
