Autumn in Korea Temperature Guide 2026 — Pack & Plan Your Trip Right

Quick Facts: Autumn in Korea Temperature & Travel

Autumn in Korea: The Real Temperature Breakdown

If you’re heading to Korea between September and November, you’re in for one of the most comfortable seasons. Autumn is famous for its crisp air, deep blue skies, and those Instagram-worthy reds and yellows from the ginkgo and maple trees. But what does “autumn” actually feel like? Here’s the deal, 2026-style:

• September: Still warm-ish. Expect daytime highs around 22°C (72°F) and nights dipping to 15°C (59°F). Short sleeves work midday, but you’ll want a light layer for evenings.
• October: Peak autumn vibes. Highs drop to 18°C (64°F), lows to 10°C (50°F). This is prime foliage time in Seoul, Nami Island, and the mountains. You’ll feel the chill if you’re out late.
• November: Getting brisk. Highs average 12°C (54°F), but nights can hit just 3°C (37°F). Foliage lingers in the south, but in Seoul you’ll see bare branches by late November. Time for a thicker jacket.

Kimi tip: Mornings and nights are much cooler than midday. You’ll thank yourself for packing layers you can add or peel off.

Step-by-Step Timeline: Autumn Trip Planning (With Temperature in Mind)

1. Booking (2–3 weeks ahead):

   • Check average temps for your travel month (see Quick Facts).
   • Book medical/beauty appointments, tours, or classes via ClassKim for real English support.
   • Ask about outdoor vs. indoor activity options—ClassKim can schedule based on the weather.

2. Packing (1 week before):

   • Layered tops, sweaters, a light to mid-weight jacket.
   • Scarf and hat for late October/November.
   • Comfortable walking shoes (city streets + park trails).
   • Compact umbrella—autumn is drier but a shower can surprise you.

3. Arrival (Day 1):

   • Airport temps will match city averages (Seoul Incheon: usually 10–20°C in autumn).
   • Have your outerwear handy for instant comfort.
   • Meet your ClassKim interpreter if you’ve booked a clinic or local experience.

4. On-Site:

   • Dress in layers for day-to-night activities (palace tour, street food, Han River stroll).
   • If you have a medical or beauty appointment, check in with ClassKim to confirm dress code (some treatments require loose/comfortable clothing).

5. Post-Visit:

   • If you do a facial or laser, the cool air is great—less sweat, faster recovery.
   • Ask ClassKim for local pharmacy or post-care instructions so you’re set for the rest of your trip.

What to Prepare: Documents, Language, Timing

• Travel Docs: Passport, K-ETA (if needed), hotel confirmation.
• Language: Most outdoor spots have limited English signage. For clinics/beauty, book with ClassKim and get a real interpreter.
• Timing:
  • Foliage: Seoul peaks mid-to-late October; Busan and Jeju peak early November.
  • Book popular activities (palace tours, Nami Island, leaf-peeping trains) in advance.

Honest Caveats: What to Watch Out For

• Temperature Swings: Daytime can feel warm, but after sunset it cools fast. You will need a jacket for night markets or river walks.
• Rain: September can see lingering typhoon effects—bring an umbrella just in case.
• Crowds: October weekends get busy at top foliage spots—book in advance or go early.
• Medical/Beauty Clinics: Not all have true English-speaking staff. ClassKim places an English interpreter on site so nothing gets lost in translation.
• Refunds & Changes: Korean clinics and tour providers have strict policies—ClassKim helps you navigate cancellations or rebooking if the weather acts up.

Realistic Expectations: What You’ll Actually Experience

• Seoul: Early autumn is t-shirt weather; by late October, you’ll want a sweater and jacket. Evenings are for cozy cafes or jjimjilbang (Korean sauna).
• Gangnam, Myeongdong: Shopping is a breeze—no summer sweat. You can hit a skin clinic and go straight to dinner in a light jacket.
• Mountains (Seoraksan, Bukhansan): Start hikes in layers; it’s chilly at the summit, especially in November.
• Jeju & Busan: Slightly warmer than Seoul, but still jacket territory after sunset.
