Weather in South Korea in January

The weather in South Korea in January is decidedly wintry. It’s cold and dry, with temperatures often dropping below freezing, especially in Seoul and the northern regions. The upside, if you’re a winter sports fan, is that snow is common, making it ideal for skiing in places like the 2018 Winter Olympics host Pyeongchang, or Yongpyong. Southern cities such as Busan are slightly milder but still chilly. Across the country, sunshine is frequent and the air is crisp, though pollution levels can occasionally spike. Overall, pack heavy coats, thermal layers and winter trunks as this is Korea’s coldest month. As you might expect, it’s also one of the quietest for tourism, making January in South Korea perfect for serene temple visits and enjoying uncrowded winter festivals.

Is January a good time to visit South Korea?

Absolutely, yes. South Korea in January is a proper winter experience. If you're into snow, seasonal festivals and sightseeing without the crowds, this is your month.

It’s the coldest time of year with dry air and low temps from top to bottom. Seoul can dip to 21°F (-6°C) while spots like Busan and Jeju Island are a bit milder at around 37°F (3°C). It’s therefore worth packing warm layers and being ready for a proper cold snap. But if you're up for snowy scenes and a slower pace, January is a brilliant time to see a different side of Korea — especially as part of a well-planned South Korea itinerary.

On that note, if you're chasing snow, head north. Gangwon-do is the go-to for skiing and snowboarding. That said, even with the chill, there are plenty of clear days and blue skies, which is perfect weather for temple visits, palace strolls and soaking up those icy landscapes.

If Lunar New Year happens in January, expect colorful traditions, family celebrations and markets buzzing with activity. And while winter has its perks, the best time to visit South Korea really depends on what kind of trip you’re after.

Average daily temperatures in January

January is full-on winter in South Korea. It’s cold everywhere, but how the temperatures go really depends on where you are.

In Seoul and the north, you’re looking at highs around 35°F (2°C) and lows near 21°F (-6°C). Snow and cold winds are common, especially in Gangwon-do where ski resorts make the most of it. Mountain spots like Pyeongchang can dip below 10°F (-12°C) at night.

Further down in places like Daejeon, it’s a bit less harsh. Highs hit 38°F (3°C) with lows at 25°F (-4°C). Still dry though with plenty of clear skies.

Down by the southern coast in cities like Busan and Yeosu, daytime temps hover near 45°F (7°C) with nights around freezing. Jeju Island stays milder with highs of 48°F (9°C) and lows around 36°F (2°C).

So yes, it’s cold but the sunshine and dry air make for fresh bright days. Whether you're heading to the slopes or exploring further south, there's something special about Korea in winter.

What about the crowd and cost?

January is a quiet time for tourism in South Korea. Major cities and cultural sites are therefore calm, with barely any lines or tourist traffic, especially outside the Lunar New Year period — an ideal window if you're planning a trip to South Korea without the crowds.

Ski resorts, on the other hand, are another story. Gangwon-do gets busy as locals and visitors head to the slopes, so it pays to book accommodation near the ski resorts as far in advance as possible. Prices in the ski resorts are at their highest at this time of the year.

On the flip side, hotels in cities like Seoul tend to be very affordable this time of year. If you're basing yourself in the capital, it’s worth knowing the best areas to stay in Seoul to make the most of your visit. Resorts and vacation hotspots are pricier though, especially around weekends and public vacations. Flights are usually good value unless you’re traveling over a vacation.
