The air in Seoul this week has that specific, crisp bite you only get in early October. It is a dry, cool chill that settles into your bones by 6:30 AM but lifts enough by noon to let the sun warm your back. I am walking through Bukchon Hanok Village right now, and while the leaves are just beginning to turn the deep reds and golds of autumn, the city feels alive with a different kind of energy. This month is not just about scenery; it is a dense cluster of national holidays, street festivals, and transit changes that will shape your days if you do not plan around them.

Weather and Packing for the Month

As of today, October 3, 2026, the forecast for Seoul is overcast with temperatures hovering between 10°C and 22°C. The key word here is swing. Mornings are noticeably chilly, often dipping near 10°C, while afternoons can feel mild and sunny. You need layers. A light jacket or trench coat is essential for the commute, but you will likely peel it off by midday. Because the humidity is low and the air is dry, fire caution advisories are active. Pack moisturizer and lip balm—your skin will thank you. If you are hiking Bukhansan National Park this weekend, bring sturdy shoes; the trails are dry and fast, but the temperature drop at the peaks (over 800 meters) is significant.

Holidays and Civic Life

You are arriving during a politically and culturally charged window. Two major public holidays fall within your stay. First, on October 5, South Korea celebrates National Foundation Day (Gaecheonjeol). While many offices close, tourist sites remain open, though you should expect larger crowds. Then, on October 9, Hangul Day (Hangeul Day) marks the creation of the Korean alphabet. Schools and government offices will be closed again. These dates create a mini-peak travel period; hotel rates may spike slightly, and domestic travelers will flood the subway lines.

Beyond the calendar, the streets are currently active with civic expression. Multiple rallies and marches are taking place across central Seoul today and in the coming days. Groups associated with the Liberty Unification Party and others are gathering at Sejong-daero, Donghwa Duty Free, Sungnyemun, Seoul Station, and Bosingak. Expect heavy congestion on Jongno and Euljiro roads between 1:00 PM and 6:00 PM. Traffic lanes are being shut down in these areas. If you are planning to walk along the main avenues during afternoon hours, allow extra time and be prepared for detours. It is a normal part of democratic life here, but it impacts logistics.

Festivals and Cultural Events

Seoul is hosting several major events that define the local rhythm right now. The most immediate impact on your movement is the Gangnam Festival, which takes over Dosan-daero from October 3 to October 5. A large street parade fills the road between Dosan Park and Hakdong intersections, closing roughly 500 meters of traffic in both directions. If you are heading to COEX or Starfield Library this weekend, avoid driving; use the subway instead.

Culturally, this is the peak of Seoul Hanok Week (October 2–11). This fourth edition transforms Bukchon and Seochon neighborhoods. You can join guided tours, exhibitions, and performances. Uniquely, visitors can enter private hanok homes that are usually off-limits, including the Swiss ambassador’s residence. Book reservation-based craft, tea, or liquor programs early—they fill up fast. For food lovers, the Car-Free Jamsugyo Bridge Festival runs every Sunday evening through October 25. Today, October 4, is the special ‘Jamsugyo Gourmet Road’ event. From 2:00 PM to 10:00 PM, the bridge becomes a pedestrian zone with over 100 food trucks. Vehicle access is barred from noon to midnight. It is a fantastic spot for sunset views and street food.

If you are interested in pop culture, I’Park Mall Yongsan is running an ‘otaku’ subculture festival until October 11. Expect cosplay photo sessions, idol and DJ performances, and a flea market for figures and characters across The Garden and The Terrace. Meanwhile, Hongdae remains the hub for indie music and busking, and Yeonnam-dong offers a quieter café scene along the Gyeongui Line Forest Park.

Transit Updates and Costs

There is one critical transit change to note: Seoul Subway Line 7’s Jangam terminus is closed for new-station construction until October 30. Trains currently turn back at Dobongsan Station. A free shuttle bus runs between Dobongsan Transfer Center, Dobong Depot, and Jangam from 5:00 AM to midnight. If your itinerary includes Goyang or northern suburbs, check your route carefully.

For getting around, ensure you have a T-money card. You can buy one at any convenience store for 2,500–4,000 KRW. The base fare for the subway is 1,550 KRW (or 1,650 KRW if paying cash for a single ride), and buses start at 1,500 KRW. If you plan to use public transport daily, consider the short-term Climate Card passes available for tourists: 1-day for 5,000 KRW or 5-day for 15,000 KRW. Note that the old monthly unlimited pass ended in September; the new resident-focused ‘Climate Companion Card Plus’ costs 62,000 KRW/month but is integrated with national refund schemes.

Eating out is affordable but rising. Everyday prices have climbed 3–5% over the past year. A bowl of jajangmyeon (black-bean noodles) runs about 7,500–7,700 KRW (~$6). A set meal of kimchi jjigae with rice and banchan is roughly 8,500–8,700 KRW (~$6). For a quick street snack, a roll of gimbap is about 3,700 KRW (~$2.7), and tteokbokki (spicy rice cakes) at a stall is 3,000–5,000 KRW (~$2.9). A hearty samgyeopsal (grilled pork belly) BBQ meal averages around 20,000 KRW (~$15).

Practical Tips for Arrival

If you are staying 90 days or less, most Western passport holders enter visa-free. However, remember that K-ETA approval is mandatory as of 2025. Apply before you book your hotel. If you are staying longer, you must register for an Alien Registration Card (ARC) within 90 days via the HiKorea portal; walk-ins are generally not accepted in Seoul.

For banking, open a passport-only account first at foreigner desks of banks like KEB Hana (Myeongdong) or Woori (Itaewon). Bring your passport, visa, and address proof. Debit cards arrive by mail about a week later. Digital wallets like Toss Bank and KakaoBank generally require an ARC, so stick to traditional bank apps initially.

Connectivity is vital. Buy a prepaid SIM at Incheon Airport from KT, SK Telecom, or LG U+, or use an eSIM service like EG SIM. A Korean number is the root dependency for everything—from KakaoTalk messages to delivery app verification. Finally, be aware that violent crime is very low, but watch for online shopping scams targeting newcomers. Use emergency numbers 112 (police) and 119 (fire/ambulance) if needed. Enjoy the crisp air and the vibrant chaos of Seoul in October—it is one of the best times to be here.
