What should I know before I arrive?

Figures checked October 28, 2026

December is the first true winter month in Korea: cold, dry days in Seoul, a milder coast around Busan and plenty of lights, skating and warm food to make up for it. VisitKorea says winter temperatures "frequently" fall below zero and advises thick outerwear at all times.

  • Worth knowing: The cold comes in cycles. Visit Seoul describes a weekly pattern of about three cold days followed by four milder ones, known as samhan saon, so the same trip can feel very different from one day to the next.
  • A common mistake: Packing autumn layers. Seoul's average high drops from 11.9°C in November to 4.2°C in December, and the average low goes below freezing.
  • Local tip: Check the forecast on the Korea Meteorological Administration site a few days before you fly, and plan indoor stops such as museums, cafes and bathhouses for the coldest afternoons.

What is the weather like in Korea in December?

Cold in Seoul and cool on the south coast: December averages 4.2°C by day and -3.4°C at night in Seoul, against 10.4°C and 2°C in Busan. These are monthly averages published by VisitKorea, so individual days can be colder, and Visit Seoul notes that winter temperatures sometimes drop to about -15°C.

Visit Seoul says heavy snow falls now and then in winter and that the Han River occasionally freezes solid, but neither official page gives December snowfall totals. Treat snow as possible rather than guaranteed.

Practical example: a visitor flying into Seoul and continuing to Busan by train can expect a gap of roughly 6 degrees between the two cities' December daytime averages, so a coat that is comfortable in Busan may be too thin for an evening in Seoul.

What should I pack for Korea in December?

Follow VisitKorea's own advice: winter jackets, gloves and scarves, plus non-slip shoes for walking on snow. A hat and thermal base layers are a practical addition based on the sub-zero night averages above, not an official requirement.

If you head to the mountains for hiking or snow, assume it will feel colder than the city figures above.

What events and activities happen in December?

Seoul's main December draws are the Seoul Lantern Festival, winter light shows, free-to-cheap ice skating at Seoul Plaza and the New Year countdown. Dates change each year, so the table shows the most recent editions on official pages and you should confirm the 2026 dates before you book.

The skating rink listed Sunday to Friday hours of 10:00 to 21:30 and Saturday and public holiday hours of 10:00 to 23:00 last season. For other winter festivals, including ice and snow events that usually fall in January and February, see our Korea festival calendar and our 5-day winter itinerary.

The Seoul Tourism guide also says recent seasons included a Christmas light show and that the Bosingak bell ringing marks the New Year at midnight; confirm the current year's arrangements on the Seoul Tourism winter page, as crowds and road closures are possible on New Year's Eve.

What are the opening hours and holiday rules?

Palaces close earlier in December and Christmas Day is a public holiday, so check each attraction's page before you go. Gyeongbokgung is the clearest example of the shorter winter schedule.

Both official pages put the last admission at 16:00, so aim to arrive well before then to see the grounds.

How do I plan a December trip?

Choose a mild base such as Busan if you dislike cold, book indoor backups for the coldest days and confirm event dates before you commit.

  1. Check the weather. Review the KMA forecast in the week before you fly.
  2. Pack for sub-zero nights. Use the list above and keep gloves and a scarf in your day bag.
  3. Confirm event dates. Look up the Lantern Festival, DDP light show and Seoul Plaza rink on the official pages once 2026-27 dates are announced.
  4. Check opening hours. Allow for 17:00 palace closing and Tuesday closures.
  5. Build in indoor time. Mix outdoor sights with museums, cafes and markets, and keep one spare day for snow or very cold weather.
