No matter where your good times happen – raucous nightclubs, ancient mountain hermitages, packed baseball stadiums, boundary-pushing museums and galleries – the chances are you’ll find something to love in South Korea. There’s no such thing as a bad time to visit, but some planning can take your trip to another level and create lasting memories.
With terrain that ranges from alpine peaks to subtropical beaches, South Korea has four distinct seasons. Knowing what to expect and how to prepare will go a long way toward getting the best out of your vacation. Here’s everything you need to know about choosing the best time to visit.
March to May: Mild Weather and Cherry Blossoms
South Korea starts to shake off its winter frost in March, and for the next three months, you can expect mild, pleasant weather. By May, cities like Seoul are warming up, with temperatures occasionally rising into the upper 20s Celsius. As a consequence, outdoor activities flourish – hikers hit the trails, bikers cycle, and Korea’s pro baseball and soccer leagues kick off.
The highlight of this season is undoubtedly the return of the cherry blossoms. These beautiful blooms begin appearing in mid-March on Jeju-do and along the south coast before reaching Seoul and Gangwon-do Province by early April. Additionally, the Jeju Fire Festival at the end of March celebrates the island’s culture.
May can see weather alternating between spring-like and summery. Koreans celebrate Children’s Day and Parents’ Day, leading to bustling amusement parks filled with families. Buddha’s birthday in May is marked in Seoul by the Lotus Lantern Festival, where brightly colored lanterns illuminate the streets.
However, it’s important to be aware of hwangsa– yellow dust from the deserts of Mongolia that occasionally mixes with local air pollution, creating less than ideal air conditions. During such times, wearing a mask outdoors is advisable.
June to August: Mountain or Beach Retreats
Summers in South Korea are long, hot, and rainy, especially in cities. The rainy season, known as jangma, begins in late June and can last through August. With temperatures close to 30°C (86°F) and high humidity levels, rain showers become frequent.
Fortunately, South Korea offers plenty of beaches and mountains to escape to during summer. Popular destinations include Seoraksan National Park and the beach town of Yangyang. Places like Busan’s Haeundae Beach see thousands flocking to cool off, while the Mud Festival in Boryeong draws summer enthusiasts eager for fun and festivities.
The summer also brings various festivals, including Korea’s two main professional sports leagues – the Korea Baseball Organization and K League – which are in full swing. The traditional holiday of Dano typically falls in June, marked by significant events like the UNESCO-listed Gangneung Danoje Festival, showcasing rich cultural practices.
On August 15, Korea celebrates Liberation Day, marking the end of Japanese colonial rule. This is also when the rain begins to ease, leading to both the Seoul Fringe Festival and the Pentaport Rock Festival in Incheon.
September to November: Ideal for Clear Skies and Autumn Foliage
Fall in South Korea is generally considered an excellent choice for travel. Pleasant temperatures and crisp air create ideal conditions for exploring the country. In fact, September is known as one of the best beach months.
While summer’s heat fades, the crowds disperse, allowing locals to head into the mountains to witness the spectacular autumn foliage that peaks in late October. Expect popular hiking trails to be busier during this vibrant time of year. In cities, the ginkgo trees transform, creating stunning golden vistas against the urban backdrop.
October is particularly special, hosting numerous festivals such as the Busan International Film Festival, Seoul Fashion Week, Andong Mask Dance Festival, Jarasum Jazz Festival, and Gwangju World Kimchi Festival. The blend of festivities and nature’s beauty makes this an unmissable month.
After October, November generally offers a quieter experience, with fewer events on the calendar. Traditionally, this month is dedicated to preparing for the winter, particularly with kimjang, the process of making kimchi. Visitors can enjoy the cool weather, ideal for hiking and sipping beverages in beautifully restored hanok.
December to February: Time for Winter Sports
Visiting Korea in winter means embracing the chill and the phrase “Choo-uh!“– meaning “it’s cold!” During this season, temperatures routinely hover near freezing, particularly in northern regions and mountainous areas.
Gangwon-do Province experiences the most snowfall, making it the hotspot for winter sports, especially after gaining international recognition during the 2018 Winter Olympics. While many areas may be quieter, ski slopes can get crowded, showcasing a different side of Korean leisure activities.
In winter, holiday celebrations such as Christmas and New Year add to the vibrant atmosphere. Notably, Seollal, the Lunar New Year, usually falls in February, when families come together for special meals and traditions. For those staying in major cities like Seoul or Busan, this is a perfect time to enjoy a unique and peaceful experience.
Food enthusiasts will find winter a satisfying season, with Korea’s rich, soup-centric cuisine reaching its peak. Indulging in delicious buchimgae (fried pancakes) in cozy venues, particularly those with traditional ondol heating, offers a comforting retreat from the cold.
