June marks the beginning of summer, one of the best times to begin your summer holiday in Korea. With daytime temperatures gradually rising but evenings remaining cool, averaging between 18°C and 26°C (64°F to 79°F), best for a stroll along the Han River and enjoying the bustling nightlife with the gentle breeze.

Though the peak of the rainy season, showers in July are usually brief rather than lasting all day, renewing both the city and lush mountains. The average temperature ranges from 22°C to 29°C (72°F to 84°F), making it a great time to enjoy city attractions while watching the rain refresh the scenery outside.

August welcomes sunny days, with temperatures between 24°C and 30°C (75°F to 86°F). The rainy season gradually recedes, and the weather becomes dry, perfect for enjoying summer activities. Seoraksan National Park and the beaches of Jeju Island remain great spots for a cool summer escape.

Crowds & Costs

Overall, South Korea sees a higher number of tourists during the summer compared to other seasons, leading to generally higher prices, particularly noticeable in late July and August.

June is relatively less crowded, especially during the rainy season (late June to mid-July), making flights and accommodations more affordable.

As the rainy season ends in late July and summer vacation begins, the number of tourists surges, particularly in popular coastal cities. Accommodation and transportation costs tend to increase during this peak period (July to August), so it's advisable to book accommodations and tickets in advance.

Where to Go in Summer in Korea

Coastal Areas: South Korea's coastal regions are perfect for summer getaways, offering refreshing sea breezes and stunning ocean views. Although summer temperatures are high, the coast often enjoys cool sea breezes, making even daytime comfortable. Busan, Gangneung, and Sokcho are great choices to experience different seaside charms and exciting water activities.

Urban Areas: Experience the vibrant energy of South Korea's major cities like Seoul, Incheon, and Daegu. These bustling metropolises offer a wide range of activities, from shopping and dining to exploring cultural attractions. And don't worry about the summer heat, as the well-equipped indoor facilities and cooler evening temperatures will allow you to comfortably enjoy city life.

Mountain & Inland Areas: Escape the hustle and bustle of the city and explore the serene beauty of South Korea's mountains and inland areas. During summer, the pleasant morning and evening temperatures in the mountains make them ideal for hiking, sightseeing, and enjoying sunrises and sunsets. Gyeongju, Andong, and Pyeongchang not only boast historical charm but also allow you to enjoy the tranquility and freshness of nature.

What to Do in Summer in Korea

Taste Summer Food

Summer food in South Korea is both varied and delicious - definitely worth a try!

Samgyetang, a ginseng chicken soup, is a signature summer dish, but you might wonder why hot soup in the heat? South Koreans believe in fighting heat with heat. This nutritious soup, made with ginseng, glutinous rice, and chicken, is believed to restore energy.

Naengmyeon, or cold noodles, is another popular summer dish. The chewy buckwheat noodles served with cold broth or sauce are absolutely excellent. And no summer in South Korea is complete without Patbingsu, a shaved ice dessert topped with various toppings like red beans and condensed milk, which is a must-try for a cool and sweet treat.

If you're eager to try these delicious foods, Jung-gu in Seoul offers numerous Naengmyeon restaurants worth exploring, while the Jongno area is dotted with long-established Samgyetang restaurants. Furthermore, various traditional markets are perfect places to find many Patbingsu.

South Korea Travel Tips in Summer

Things to Pack

When packing for your summer trip to South Korea, opt for lightweight and breathable clothing like t-shirts, shorts, and dresses. Be sure to pack sunscreen, sunglasses, and a hat to protect yourself from the sun. If you plan on visiting the beach, don't forget your swimsuit and sandals. Since the rainy season brings unexpected rains, a foldable umbrella or a lightweight raincoat is essential. A handheld fan can also help you stay cool.

Avoid the Midday Sun

The midday sun in South Korea during summer makes outdoor activities tiring and even causes sunstroke. The best way to stay cool is to avoid going out at noon and plan activities for the morning or evening. Alternatively, enjoy indoor spots like malls, cafes, or museums. If you need to be outside, be sure to wear sunscreen, sunglasses, and a hat, and drink plenty of water to prevent dehydration.

Book Early

Summer is peak travel season in South Korea, if you're planning a trip during this time, it's advisable to book your accommodation, transportation, and tickets to popular attractions several weeks or even months in advance.
