Introduction
If you're planning a trip to Seoul, one of the first questions you might ask is:
When is the best time to visit Seoul?
One thing people quickly notice about Seoul is how different the seasons feel. The city looks completely different in spring, summer, autumn, and winter.
From cherry blossoms in spring to colorful autumn foliage and snowy winter streets, the atmosphere of the city changes dramatically throughout the year.
Because of that, the “best” time to visit really depends on what kind of trip you're planning.
As a local, I can say that every season has its own charm. Some months are perfect for walking around palaces and parks, while others are great for festivals, food, and unique seasonal experiences.
In this guide, you'll learn what each season in Seoul is like, the best months to visit, and a few local travel tips to help you plan the perfect trip.

Quick Answer: Best Months to Visit Seoul
If you're looking for a quick answer, the best times to visit Seoul are generally:
- April – May (spring weather and cherry blossoms)
- September – October (cool temperatures and autumn foliage)
During these months, the weather is comfortable, the skies are often clear, and many of the city's parks, riversides, and palace grounds look especially beautiful.
However, each season in Seoul offers something unique, so the best time to visit can also depend on your travel style.
Spring in Seoul (March – May) : Cherry Blossom Season
Spring is one of the most popular times to visit Seoul, especially during cherry blossom season.
Around early April, the city becomes filled with soft pink and white blossoms. Parks, riversides, and palace grounds turn into beautiful walking areas, and many locals go outside to enjoy the weather.
Some of the most famous cherry blossom spots include:
Yeouido (one of the most famous cherry blossom festival areas), Seokchon Lake near Lotte World and historic palaces like Gyeongbokgung.
Spring temperatures are usually mild, ranging from 10°C to 20°C (50–68°F), which makes it a great season for exploring the city on foot.
Another fun thing about spring is that Seoul hosts seasonal events such as the Seoul Spring Festival, which typically runs from early April to early May across parks along the Han River.
If you're planning to explore the city during cherry blossom season, using the Seoul subway is the easiest way to visit popular viewing spots.
Why visit Seoul in spring
- Cherry blossoms and flower festivals
- Pleasant temperatures for sightseeing
- Beautiful parks and palace scenery
- Many outdoor events and seasonal festivals
Because of the blossoms, early April is usually the busiest time for tourists, so booking hotels a little earlier is a good idea.
Summer in Seoul (June – August) : Festivals and Nightlife
Summer in Seoul can be lively, energetic, and full of nightlife — but it is also hot and humid.
Temperatures often reach 30°C (86°F) or higher, and from July to early August the city experiences the rainy season known in Korea as “jangma.”
As a local, I’ll be honest: summer is usually the least recommended season for outdoor sightseeing because the humidity can be intense. Many visitors end up spending more time indoors searching for air-conditioned cafés, malls, or museums.
That said, summer still has its own fun atmosphere.
Evenings become very active, especially along the Han River, where locals enjoy:
- Riverside picnics
- Food deliveries to the park
- Bike rides and night walks
Seoul also hosts several summer festivals, such as:
- Seoul Park Music Festival
- Waterbomb Festival (a popular summer music and water event)
Why visit Seoul in summer
- Vibrant nightlife and street food culture
- Summer music festivals and events
- Lively evening atmosphere along the Han River
If you don't mind the heat and humidity, summer can still be a fun and energetic time to experience the city.
Autumn in Seoul (September – November) : Fall Foliage
Autumn is often considered the best overall season to visit Seoul.
The weather becomes cooler and much drier than summer, making it ideal for exploring the city. Temperatures usually range between 10°C and 22°C (50–72°F).
During October and early November, the city fills with red, orange, and golden autumn leaves, creating beautiful scenery across parks, mountains, and palace grounds.
Popular spots for autumn foliage include:
- Namsan Seoul Tower
- Large city parks
- Palace gardens
- Walking trails around the city
Because the weather is so comfortable, many locals enjoy picnics, walks, and outdoor cafés during this season.
Seoul also hosts seasonal events like the Seoul International Garden Show and other autumn cultural festivals.
Why visit Seoul in autumn
- Comfortable weather for sightseeing
- Stunning fall foliage across the city
- Clear skies and beautiful city views
- Great season for walking and photography
For many travelers, October is the single best month to visit Seoul.
Winter in Seoul (December – February) : Snow and Street Food
Winter in Seoul can be very cold, and temperatures often drop below −5°C (23°F).
However, the city also has a unique charm during the winter months. Snow-covered palaces and quiet streets create a beautiful atmosphere, especially around historic areas.
Winter is also a great season to experience Korean winter food, festive lights, and seasonal markets.
Some fun winter experiences include:
- The Seoul Lantern Festival along Cheonggyecheon Stream
- Ice skating at Seoul Plaza in front of City Hall
- Enjoying warm Korean street food like hotteok and fish cake
Another advantage of visiting Seoul in winter is that there are usually fewer international tourists, which means popular attractions can feel less crowded.
Why visit Seoul in winter
- Fewer tourists at major attractions
- Holiday lights and winter festivals
- Seasonal Korean street food
Just be sure to pack very warm clothing, since the cold wind can make temperatures feel even lower.
When to Avoid Visiting Seoul
There is no truly bad time to visit Seoul, but some periods can be less comfortable for travel.
Late July to early August can be extremely humid because of the monsoon season, and heavy rain sometimes lasts several days.
Hotel prices may also increase during major Korean holidays such as:
- Chuseok (Korean Thanksgiving)
During these holidays many locals travel across the country, which can cause transportation delays or higher accommodation prices.
Checking the Korean holiday calendar before planning your trip can help avoid surprises.
