After the searing temperatures and exhausting humidity of Korea in August, we all breathe a collective sigh of relief in Korea in September. It’s one of the best months to visit Korea — and if you time it right around Chuseok, it can be a unique cultural experience you’ll never forget.

TITLE: 🇰🇷 Korea in September: Quick Travel Snapshot INTRO_START September is one of the best months to visit Korea, but don’t expect an immediate escape from the summer heat. Early September can still feel hot and humid, with temperatures only gradually easing as the month progresses. By late September the air is noticeably fresher, skies are clear and blue, and the country comes alive with festivals and outdoor events. The one thing to plan around is Chuseok — Korea’s biggest holiday — which triggers a massive travel surge and can shut down businesses for several days.

If you’ve planned your trip to South Korea for September, you’re in for a wonderful time! Golden light, comfortable weather, and a city that finally feels like it’s breating again after the summer. It’s easy to feel optimistic this month.
Whether it’s challenging yourself with a hike up Bukhansan, seeing the sights from the deck of a luxury yacht on the Han River, or scooting around Seoul on an e-bike, September is definitely a month to spend as much time outdoors as possible.
In Korea in September, kids are back in school, and the crowds chasing peak autumn foliage haven’t arrived yet. So booking tours and the ideal accommodation in Seoul is relatively easier, and more affordable than in October and November.
The one thing to plan carefully around is Chuseok, one of Korea’s biggest holidays, which falls on September 25th in 2026 with holiday dates running from the 24th to the 26th. The travel surge around those dates is significant, businesses close, and transport books out incredibly fast. More on that below.
There’s also plenty to keep you entertained in September (가을, gaeul), with some truly unique festivals and events set to take place in this first month of autumn. I’ll cover those a bit further on in this guide.
What’s the weather like in Korea in September?
After the oppressiveness of summer in Korea, the September weather feels just a little bit like heaven. This used to reliably be one of the best months to visit Korea climate-wise, with ideal temperatures, minimal humidity, and glorious sun-filled days… but I’m afraid it’s no longer the case.
Global warming is wreaking havoc on our usual weather patterns unfortunately, so it’s best to prepare for some hot and humid days this month too.
However, there IS still an overall cooling trend in Korea during September, with daytime high temperatures decreasing 4°C | 8°F, from 27°C | 81°F to 23°C | 73°F over the course of the month.
It’s still hot enough across the country to be out in shorts and t-shirts for the first few weeks of September in Korea, but it’s wise to prepare a sweater or light jacket for evenings. Near the end of the month, it can feel downright chilly at night, with average lows of 17°C | 63°F.
Weather in Korea in September: Breakdown by Major Cities
C1_NAME: Seoul C1_LOW: 17°C (63°F) C1_HIGH: 26°C (78°F) C1_RAIN: 130 mm (5.12 in) C2_NAME: Busan C2_LOW: 19°C (66°F) C2_HIGH: 26°C (78°F) C2_RAIN: 135 mm (5.31 in) C3_NAME: Jeju Island C3_LOW: 20°C (68°F) C3_HIGH: 27°C (80°F) C3_RAIN: 150 mm (5.91 in) C4_NAME: Gyeongju C4_LOW: 16°C (61°F) C4_HIGH: 25°C (77°F) C4_RAIN: 120 mm (4.72 in)Seoul Weather in September
With average temperatures ranging from 17°C | 63°F to a still warm 26°C | 78.°F, the Seoul weather in September is simply wonderful. It cools down as we head into Seoul’s incredible autumn season, but jeans and multiple layers are all that’s required for exploring comfortably this month.
The humidity decreases quickly in Seoul in September, and by the end of the month, it sits at just 3%. There are about 9 days of rain, totalling approximately 170-mm, on average, but it’s not really anything to worry about.
*Personal note: Last year, it stayed hot and humid during the day time right up until the end of September. It started to cool down a little in the last week, with evenings and nights pretty tolerable. Is this new September weather, or was it an outlier? We will have to wait and see.

Korea Travel Essentials
Don’t board that plane to Seoul until you’ve sorted out accommodation, transport from the airport, and your data on the ground.
Busan Weather in September
With its location on Korea’s southeastern coast, Busan in September is usually cooler than Seoul. It has average daily temperatures ranging from 21°C | 70°F to 24°C | 76°F. It rains for approximately 9 days, but precipitation only totals about 70-mm over the entire month.
If you don’t mind a cooler sea, it’s still possible to swim at Busan’s beaches. The water temperature sits at 25°C | 77°F in September in Korea, and there’s plenty of sunshine to enjoy. Be sure to slather on that sunscreen though – the UV index is still very high.
BUSAN ONE DAY TOURS | Major attractions like Taejongdae Cliff, Songdo Skywalk, Gamcheon Culture Village, and Haedong Yonggungsa Temple are spread out in several different areas of Busan. Make it easy with by joining a one day tour. Check options here.
Jeju Weather in September
In September, average temperatures on Jeju Island range from 20°C | 69°F and 26°C | 78.4°F with 11 days of rain, totalling approximately 220-mm of precipitation.
The water temperature is 25°C | 76°F, so you can still swim comfortably at one of Jeju’s gorgeous beaches.
TITLE: JEJU ISLAND TRANSIT AND LOGISTICS SNAPSHOT INTRO_START Public transit on Jeju Island is not nearly as efficient or fast as in Seoul. Distances are long and bus routes are slow, so planning your transportation ahead of time is critical to maximizing your itinerary—especially during the busy September Chuseok holiday week when local rental cars book out completely! INTRO_END ITEM: Car rentals are highly recommended but require an International Driving Permit (IDP) booklet. ITEM: You must present your physical IDP booklet, native driver’s licence, credit card and passport at the rental counter. ITEM: If you prefer not to drive, hiring a INLINE_LINK is your best alternative. ITEM: Private car charters with local drivers are widely available for completely custom travel routes.

The Korea weather in September on East Coast beaches is typically quite a bit cooler than in the interior.
In Gangneung in September, the average daily temperatures range from 16°C | 60°F to 21°C | 70.5°F. The sea temperature hovers around 22°C | 71.2°F – which makes for uncomfortable swimming, for most people.
In my experience. the East Coast can feel quite chilly even in summer time, so be prepared with some heavier weight clothing.

Korea in September | Typhoons
Typhoon season in South Korea is from July to September. At this time a few years ago, Typhoon Hinnamnor was barreling towards Jeju Island. It was at Korea’s highest typhoon rating, with a maximum wind speed of 55-m per second – strong enough to collapse a building.
If a typhoon should hit while you’re visiting Korea in September, it’s best to stay indoors, shut the windows tight and avoid places where there could be flooding or mudslides… and maybe avoid Jeju Island. A lot of flights get cancelled or delayed there at difficult weather times.
EMOJI: 🌪️ LABEL: AUTUMN TYPHOON SAFETY IN SEPTEMBER BODY_START While September marks the start of gorgeous autumn weather, it is also historically the primary month for late-summer typhoons in South Korea. These tropical storms can bring heavy wind and intense rainfall, occasionally disrupting high-speed rail lines or coastal ferry schedules. To track official real-time safety alerts while on the ground, download the government’s Emergency Ready App and monitor the Korea Meteorological Administration (KMA) website closely. BODY_END BTN_TEXT: Download the Official Government Emergency Ready App Here → BTN_URL: https://safekorea.go.krPublic Holidays in Korea (September 2026 Travel Tips)
There is one major public holiday in Korea in September, and it’s one of the biggest of the entire year.
Chuseok | 추석
Chuseok is Korea’s harvest festival, often compared to Thanksgiving in North America or the Mid-Autumn Festival across East Asia. It’s a time when Koreans return to their hometowns to celebrate with family, pay respects to ancestors, and share traditional food like songpyeon (송편), a rice cake filled with sesame, chestnut, or red bean.
The official public holiday runs from September 24th to 26th, but the travel surge begins several days earlier and continues after. It (along with Seollal) are the single most disruptive travel events of the Korean calendar.
What this means practically:
- KTX train tickets are sold at a certain date and time for the Chuseok holiday
- Jeju flights book out fast and prices spike significantly
- Many smaller restaurants, local shops, and some attractions close for the duration
- Seoul’s streets can feel surprisingly quiet during the holiday itself, while transport hubs are absolute chaos
The flip side is that Seoul’s palaces, the National Folk Museum, and various cultural venues put on special Chuseok programming that’s worth experiencing as a visitor.
EMOJI: 🚨 LABEL: TRAVEL ALERT | CHUSEOK HOLIDAY CRUNCH — SEPTEMBER 24TH–26TH 2026 BODY_START Chuseok is one of Korea’s biggest holiday and one of the most disruptive travel events of the year. On and around September 24th–26th, up to 30 million people travel simultaneously across the country. KTX trains, express buses, and flights to Jeju sell out weeks in advance. Many restaurants, shops, and attractions close entirely for the duration. If you’re travelling between cities or heading to popular destinations like Jeju, Gyeongju, or the East Coast during this period, book everything before you fly. BODY_END BTN_TEXT: Check Hotel Availability for Chuseok Week → BTN_URL: https://booking.tpk.ro/YVA2a3sDThings to Do in Korea in September
September is the month Korea finally exhales. The heat starts to break, the skies clear, and suddenly everything that felt too exhausting in July and August becomes enjoyable again. It’s one of the best months of the year to simply be outside.
Experience Chuseok
Chuseok falls on September 25th in 2026, with public holiday dates running from the 24th to the 26th.
If you’re in Korea at this time, make sure to experience traditional folk games, ancestral rites, and special cultural performances across the country. Seoul’s palaces and the National Folk Museum put on some of the best free events of the year during Chuseok. Just plan your transport carefully, and maybe plan to stay put in Seoul. The country moves en masse during this holiday.
Chase Pink Muhly and Cosmos
September in Korea marks the beginning of the pink muhly grass season, one of the most gorgeous natural events of the year.
Most of the pink muhly was removed from Seoul a few years ago, but you can still see it at various spots around Gyeonggi-do and around the country. Two of my favourite spots to see pink muhly in Korea are Yangju Nari Park and Goseokjeong Flower Garden.
Cosmos fields also start blooming in late September, adding bursts of colour to the landscape before the full autumn foliage arrives. Check it out at Olympic Park in Seoul.
Get Back Outside
Hiking, cycling, picnics, and palace visits all come back in September.
Bukhansan is magnificent on a clear September day, the Han River parks fill up with locals enjoying the cooler evenings, and the city’s outdoor spaces feel alive again in a way they simply don’t during the summer months.
Catch the Palace Night Tours
The Gyeongbokgung Starlight Tour and Changdeokgung Moonlight Tour typically open again in September, though exact dates are announced late. These are among the most sought-after experiences in Seoul and sell out within minutes of tickets going on sale.
I’ll update on Instagram the moment they’re announced. Make sure to book on Creatrip (the exclusive distributor for foreigner tours) the moment they drop.
Take a Day Trip Before the Crowds Arrive
September is the sweet spot for day trips outside Seoul. The autumn foliage crowds that descend in October haven’t arrived yet, so Nami Island, Seoraksan, Gyeongju, and the East Coast are all accessible without the chaos of peak season. Prices are lower and accommodation is easier to find.
September also has a solid festival lineup, from drone light shows to fashion week to cultural celebrations. See the full breakdown in the section below.
Essential Day Tours from Seoul
Seoul is one of the best cities in the world for day trips. Within two hours of the city centre, you’ll find UNESCO fortresses, national parks, island getaways, and one of the most unique border zones on earth. September is an ideal month for all of them. The weather is comfortable, the crowds are thinner than they are in October, and if you’re lucky, the autumn colours might just start to appear at higher elevations.
These are the day trips consistently worth doing, regardless of the time of year, and each has a real reason why.

Parts of the DMZ MUST be visited on a guided tour, due to security clearances, and September in Korea is the perfect month to go, since the weather is comfortable.
Hwaseong is a majestic UNESCO Fortress, that is excellent to visit with the Korean Folk Village, but both are in satellite cities south of Seoul.
Nami Island and nearby attractions are the most popular day tour near Seoul, but they’re spread far apart, with terrible public transit connections. Joining a day tour makes total sense, especially given the huge range of add ons to choose from, like Alpaca World, the Rail Bike, and Garden of Morning Calm.
Korea in September | Best Festivals and Events
When September hits Korea, it’s like we all wake up from a deep summer hibernation, fully recharged and ready to explore the country. The streets are packed and the mood is vibrant.
This list is by no means exhaustive, but here’s a rundown of some of the major festivals and events to check out in Korea in September.

Best of all, Seoul Light is free to see! I’ve personally gone to Seoul Light a few times, and been completely awestruck. Shows start at 7:30PM, and run until 10:00PM.

This is a totally free event taking place at various Hangang Parks around Seoul.
Exclusive Royal Palace Night Tours & Cultural Celebrations
September in Korea is prime time for deeply traditional cultural heritage events, especially as the mid-autumn holiday season approaches. Because night tour openings are rare and highly restricted, they definitely require a bit of strategic planning to secure.

You could think of Chuseok as a Korean Thanksgiving, since it’s a vital holiday where family members travel from all corners of the country to gather in their hometowns, share a festive feast, and honour their ancestors through traditional rituals like Charye and Seongmyo.
For travelers, Chuseok is an excellent time to learn about Korea’s culture, by playing traditional games, eating songpyeon, and watching folk performances. Check out my full guide on what to do in Seoul during Chuseok for some ideas.

Trying to do it independently using public transport is often time-consuming and more expensive, so joining a day tour is the easiest and most affordable way to see them. Check them out here!

September in Korea is a shoulder month between summer and autumn. The weather can change quickly from hot to windy and cool this month, so it’s best to be prepared with multiple layers and weights of clothing to deal with the changing conditions.
At the beginning of the month, temperatures are still relatively high, the sun is strong, and there’s some possibility of rain. I’m comfortable in shorts and t-shirts, even in the evenings, but I run pretty hot. Most locals are wearing jeans, leggings, skirts, long-sleeved shirts, and lighter weight sweaters, jackets, and windbreakers by the start of September in Korea.
By the end of the month (or even earlier), it’s cooled down enough that shorts and sandals would feel strange. Travellers from tropical climates would probably find it chilly, especially at night.
You’ll log a lot of miles while exploring Korea, so comfortable shoes are a must. A quality pair of sneakers or running shoes will save your feet when tackling all the stairs and steps in Seoul.
What to Pack for Korea in September (And What to Buy When You Get There)
Keep in mind that this is a shoulder month, and you’ll need warmer items if you’re traveling to Korea in the latter half of September.

▼ It’s cooler at the end of September in Korea than at the beginning, so prepare accordingly. If you’re visiting in the first week of September, there’s a higher chance of rain, but you can pick up an umbrella easily here.
▼ Koreans generally dress quite well. You’ll stand out quite a bit if you’re wearing a “typical backpacker“ look.
▼ It’s best to dress on the conservative side, if you don’t want to draw unwelcome attention. For women, a low neckline will attract eyes, but a super short skirt won’t (go figure).
wow, yeash yeash South Korea in September is pleasing.
Love the photographs. <3
September is SUCH a relief after summer. I feel like I’m alive again. Ha!
