Visiting Korea in May | Weather, What to Wear + Best Spring Festivals [UPDATED 2023]

All the freshness and cherry blossoms of Korea in April might be finished, but Korea in May is the true height of spring. Warm sunshine and bright flowers paint the country in a rainbow of kaleidoscopic colour that’s just as stunning as all that pink.

May brings flowers and sunshine to Korea.

In this guide, you’ll learn:

• what the weather is like during May in Korea
• the Seoul weather in May and other major cities and tourist hotspots, including Busan, Sokcho, and Jeju
• the best spring festivals to attend around the country in May
• what to wear and the best things to pack for a successful trip to Korea in May

Visiting Korea in May

Some would say that May is the absolute best time of the year to visit Korea. The heaving crowds from peak cherry blossom season have left, and summer vacations haven’t started yet, so booking tours and accommodation in Seoul is much simpler.

May is the ideal time for outdoor activities in Korea

There’s also plenty to keep you entertained, with some of the year’s best festivals occurring in the month of May. I’ll cover these a bit later on in this guide.

The May weather in Korea is pretty much ideal. So whether you choose to hike up Bukhansan, or take a leisurely stroll around Seokchon Lake Park, this is definitely the month to get outdoors and explore the delights of nature.

Korea in May | Weather

The warming trend of spring continues in Korea during May, with daytime temperatures reaching as high as the mid-20s°C | high 60s°F by the end of the month. May (along with October) is one of the best months to visit Korea climate-wise, with ideal temperatures, little humidity, and long, sunny days.

The weather is pretty much perfect in May.

In May, average daily temperatures in Korea range from 13°C | 55°F to 23°C | 73°F across the country. There’s some humidity, but the gross mugginess brought by summer monsoons have yet to hit the Peninsula, and it’s a very pleasant time to be in Korea.

Korea in May | Seoul Weather

Seoul in May is pretty indicative of the weather all over the country. The average temperature increases 6°C from April, up to 17°C | 63°F. Highs can reach up to 25°C | 77°F by the end of the month. You can expect an extra 60 to 90 minutes of daylight in Korea in May, with many of those hours filled with blue skies and bright sunshine.

May is the perfect month to rent a hanbok in Seoul and tour palaces comfortably.

The Seoul weather in May has increasing humidity, but it still doesn’t feel overly humid or uncomfortable yet. There are about 6 days of rain (mostly concentrated at the end of the month), totalling approximately 100-mm, on average.

Korea Weather in May | Busan

Busan is located on the southeastern coast of Korea, so it’s slightly warmer than Seoul in May. It has average daily temperatures of 15°C | 59°F to 22°C | 72°F. In Busan, the Korea weather in May is relatively rainy, with an average of 9 days of rain per month, totalling approximately 157-mm of precipitation.

Korea Weather in May | Sokcho (East Coast)

The Korea weather in May on the East Coast beaches is typically a bit cooler than in the interior. Sokcho in May has average daily temperatures ranging from 12°C | 54°F to 17°C | 63°F. In my experience. it can feel pretty chilly, especially with those sea breezes, so be prepared with some heavier weight clothing.

There’s more days of rain in Sokcho in May, but less overall precipitation relative to Seoul and Busan. There’s still plenty of sunshine to enjoy.

Korea Weather in May | Jeju Island

Jeju has a temperate humid climate, but in May, temperatures are not much different than in Seoul. Averages range from 14°C | 57°F to 22°C |72°F, with 10 days of rain, totalling around 100-mm of precipitation.

May is a gorgeous time of year to visit Jeju Island.

Overall though, May is an absolutely wonderful time to visit Jeju Island. Nature is at its most verdant, and the Korea weather in May on Jeju is perfect for the many outdoor activities available on the island.

Korea in May | Air Quality

In Korea in May, there are fewer bad air days compared to April, but it’s still a depressing factor.

As spring begins in Korea, windstorms originating in the Gobi Desert, travel across China and land squarely on top of the ROK, in the form of yellow dust. Called “hwangsa,” in Korean, it colours the sky, in a murky yellowish fog. And it’s full of ultrafine and fine dust pollution.

Yellow dust and pollution can be an unfortunate part of visiting Korea in May.

If you’re visiting Korea in May, be sure to equip yourself with some kind of air pollution mask, and allergy meds if you need them. There’s no need to prepare too many masks in advance. You can pick up high-quality disposable air pollution masks in any pharmacy, convenience store or Daiso in Korea for as low as 500 won each.

The Korean equivalent of an N95 mask is called KF94. If that feels too hot and heavy for the Korea weather in May, you can get a KF80 mask instead. This will factor out 80% of pollutants, so it’s not perfect, but it’s still better than nothing.

Masks have been an unfortunate part of life for too long now.

Limited Edition Spring Tours in Korea

Plum blossoms in Gwangyang Maehwa Village are usually the first sign of spring in Korea, with petals bursting into bloom from mid-March. Like cherry blossom season, the dates for most spring tours in Korea is incredibly limited. Most run for just a few short weeks, so catch them while you can.

May is a comfortable time to rent a hanbok and visit Gyeongbokgung Palace.

Of course, you can skip the ticketing process entirely, and walk straight into Gyeongbokgung for free, if you’re wearing a hanbok. It’s actually the perfect time to try it out, since the Korea weather in May isn’t too hot or cold.

In combination with Nami Island and the Gangchon Rail Bike, the Garden of Morning Calm is one of the most popular day tours from Seoul, with good reason. I’ve visited these places multiple times myself, and they are definitely worth the trip – especially in Korea in May, since the weather is pretty much perfect.

Royal Culture Festival | 궁중문화축전

Admissions into all palaces will be free on the first day of the festival.

On the opening day of the festival, all palaces will be free to enter. Stop by Cheong Wa Dae – the Presidential Residence – which has been fully open to the public since last year.

Despite being near the top of an 1108-metre mountain, Hwangmaesan County Park is very accessible. It’s an easy hike up to the peak, or you can simply drive up to the fields instead. There’s parking nearby.

Main events mostly happen during May in South Korea. They include the Seoul Culture Square at Gwanghwamun, and the Seoul Bridge Taste Market on Jamsu Bridge, but there are SO many other things happening, from Taekwondo demonstrations to busking to a circus.

In Korea in May, there’s a Gyejoksan Mountain Barefoot Festival, where participants are encouraged to take off their shoes and run or walk barefoot along the 14.5-km trail.

There are a number of separate events to attend during the festival, including a lighting ceremony, cultural performances, traditional lantern exhibition, and lantern making experiences.

The highlight is undoubtedly the Lotus Lantern Parade, where literally thousands of Buddhists carry lovely glowing lanterns, along a route that starts at Heunginjimun Gate and ends at Jogyesa Temple. It starts at 7:00PM, but I suggest arriving a bit earlier to get a good spot on the parade route.

Show up early to get a good spot on the parade route. Your kids can play tag on the street.

On May 21st, you can participate in cultural events like lantern making, and watch traditional performances, while eating favourful temple cuisine. All events will be held on the street directly in front of Jogyesa Temple.

If you can’t make it to Yeon Deung Hoe on either of those days, you can still see traditional lanterns colourfully displayed at Jogyesa Temple, Bongeunsa, and Gwanghwamun Square for another few weeks.

Lanterns will be on display at Bongeunsa, Jogyesa, and Gwanghwamun Square until May 28th.

Haeundae Sand Festival | 해운대 모래축제

Festival Dates: May 19th – 22nd, 2023

Address: U-dong, Haeundae-gu, Busan | 부산광역시 해운대구 우동

During May in Korea, large-scale sand sculptures take over Haeundae Beach in Busan. Be amazed by the fine detail and artistry of these fleeting pieces of art, and take part in experiential programs like sand-boarding or a sand treasure hunt at the festival.

Sand sculptures are amazing pieces of art.

If you can’t make it to Busan for the actual festival dates, don’t worry! Sand sculptures will be on display until June 6th. That is, unless it gets washed away by a typhoon or unexpected rainfall…

Chuncheon Mime Festival | 춘천마임축제

Festival Dates: May 28th – June 4th, 2023

Address: Various locations around Chuncheon-si, Gangwon-do | 강원도 춘천시 전역

The Chuncheon Mime Festival is set to take over the city of Chuncheon in the last week of May. This is just one of 3 major mime festivals in the world, attracting performers from mime troupes from all over the world.

At the festival, you’ll see innovative non-verbal mime and street performances that even non-Korean speakers can enjoy.

Ride along abandoned trail tracks and tunnels on the Gangchon Rail Bike.

If you’re looking for more to do in the area, you could combine a visit to the Mime Festival with a visit to the nearby Nami Island or Gangchon Rail Bike, which are 2 of the most popular day trips from Seoul.

Korea in May | What to Wear

To best deal with Korea’s weather in May at the beginning of the month, jeans, leggings, skirts, and long-sleeved shirts, tees, or lighter weight sweaters work well. Bring along a hoodie, cardigan or light jacket for cooler evening temperatures.

By the end of the month (or even earlier), it’s warm enough for shorts and t-shirts for those used to cooler temperatures. Travellers from tropical climates might still find it a bit chilly, especially at night.

By the end of May, it’s warm enough to wear shorts and t-shirts

There is some precipitation, but it’s not really enough to worry about, unless you’re visiting in the very last week of May. This is when the bulk of rainfall happens as we head into summer monsoon season, so it’s helpful to have waterproof shoes or quick-dry clothing. I wouldn’t recommend wearing a raincoat at the end of May in Korea, as it could be hot and uncomfortable.

May is the perfect month for hiking the many Dulegil around Korea.
