What should I know before I arrive?
Information checked October 3, 2026
Korea has four distinct seasons, and spring and autumn are the easiest times to visit. VisitKorea describes the climate as temperate with four distinct seasons: clear and mild in spring and fall, hot and humid in summer, and cold and dry in winter.
- Worth knowing: August is the warmest month and January the coldest, and yearly averages run from 7°C at Daegwallyeong to 15°C in Busan (VisitKorea).
- A common mistake: Planning around a single date. Blossom and foliage dates shift with the weather, so choose a window of a week or two and check the official forecast near departure.
- Local tip: Dress in layers in spring and autumn, when mornings and afternoons differ widely.
Which season is best for visiting Korea?
Spring (April to June) and autumn (September to October) suit most travellers, because they are mild and dry compared with summer and winter. The right season still depends on what you want to do, so use the table as a starting point.
| Season | Seoul figures | Good for | Watch out for |
|---|---|---|---|
| Spring (March to May) | Mean 5.7°C in March, 17.8°C in May (Visit Seoul); May high 23.6°C, low 13.5°C (VisitKorea) | Cherry blossoms, flowers, palace visits | Occasional sand storms; changeable temperatures |
| Summer (June to August) | August mean 25.7°C; high 30°C, low 22.9°C; about 383 mm of rain in July | Beaches, water sports, Hangang River activities | Heat, humidity, the rainy season and typhoons |
| Autumn (September to November) | October high 20.2°C, low 10.6°C | Foliage, clear skies, festivals, Chuseok | Typhoons can still occur until October; popular sites get crowded |
| Winter (December to February) | January high 2.1°C, low -5.5°C; can fall to about -15°C | Skiing, hot springs, snowy parks, Seollal | Sub-zero temperatures; heavy outerwear needed |
What is Korea like month by month?
March to May warms from cool to comfortable, June to August brings rain then heat, and October to November turns crisp and colourful. The notes below use the official figures above and general seasonal patterns, so treat them as approximate.
- January and February: Coldest part of the year. Seoul's January high is 2.1°C and the low -5.5°C, and Seoul's tourism site describes Samhan Saon, a pattern of three cold days followed by four milder ones.
- March: Still cool, with a Seoul mean of about 5.7°C. Cherry blossoms reach the south first: in 2026 the forecast bloom date was March 25 for Jeju and Busan.
- April: Blossom month in Seoul (forecast April 3 in 2026, full bloom about April 10). Bring layers.
- May: Among the most comfortable months, with a Seoul high of 23.6°C and low of 13.5°C.
- June: Warm and humid; the rainy season can start in mid-June.
- July: The wettest month in Seoul, at about 383 mm of rain, according to Visit Seoul. Carry a light rain jacket and an umbrella.
- August: The hottest month, with highs around 30°C and high humidity.
- September: Autumn begins and temperatures ease, but typhoons remain possible until October.
- October: Seoul's high is 20.2°C and the low 10.6°C. Colour starts on the northeastern mountains.
- November: Peak colour moves south. The 2026 VisitKorea forecast puts Naejangsan at November 11 and Hallasan at November 13, and temperatures fall steadily.
- December: Cold and dry, with ski season, hot springs and warm food at their best.
Practical example: a first-time visitor who wants easy sightseeing without extremes could book the first half of May or the second half of October, then add a rain jacket and a light fleece.
When are the rainy season and typhoons?
The rainy season runs from late June to late July, and typhoons can occur between June and October. VisitKorea gives the late June to late July window, while Visit Seoul says the jangma rains typically begin in mid-June and last about a month.
- Plan indoors: Keep museums, markets with roofs, shopping malls and cafes on your list for wet days.
- Check forecasts: VisitKorea advises summer visitors to check the weather forecast in advance because of typhoon and heavy-rain risk. The Korea Meteorological Administration publishes official forecasts and warnings in English.
- Stay flexible: Choose refundable or changeable bookings for travel between June and early October.
When do cherry blossoms and autumn leaves peak?
Cherry blossoms usually bloom from late March to early April, and autumn colour peaks from late October to mid-November. Both move from south to north or from mountains to lowlands, and both shift each year with the weather.
- Blossoms: The 2026 VisitKorea forecast gave Jeju and Busan March 25, Gangneung April 1 and Seoul April 3, and said peak bloom comes about a week after flowering begins (around April 10 in Seoul). Seoul's tourism site also mentions the Yeouido cherry blossom festival.
- Autumn colour: Our guide to autumn foliage in Korea lists the 2026 forecast peaks, such as Seoraksan around October 25 and Bukhansan on November 4.
- Dates move: Always read the latest official forecast within a week or two of your trip.
Is winter a good time to visit Korea?
Yes, if you like snow, skiing and hot springs and you pack properly. VisitKorea highlights winter sports such as skiing and snowboarding, along with hot springs, ondol (heated floor) culture and warm soup dishes, and warns that thick outerwear is needed for sub-zero temperatures.
- What to pack: A warm coat, thermal layers, gloves and a hat. Visit Seoul says temperatures can drop to about -15°C.
- Holiday timing: Seollal (Lunar New Year) falls in winter, and Chuseok in autumn. These are family holidays, so check dates and expect busy transport, as noted on Visit Seoul.
How do I choose the right month for my trip?
Pick your top priority first, then match it to the months above.
- Decide your priority. Blossoms point to late March and April, comfortable walking to May or October, foliage to late October and November, snow to December through February.
- Check the weather risk. Avoid the rainy season (late June to late July) if you want dry sightseeing, and allow flexibility from June to October for typhoons.
- Check holidays and crowds. Look up Chuseok and Seollal dates for your year before booking flights and trains.
- Read the live forecast. Review official blossom or foliage forecasts and the KMA weather pages within a week of departure.
- Plan the route. Once the month is set, see Seoul in 3 Days and Incheon Airport to Seoul for the first leg.
