Introduction: The Most Energetic Season in a Country of Four Seasons
Hello, dear readers! Today, I'd like to talk about how to experience summer in Korea.
Korea is well known for having four distinct seasons: spring, summer, fall, and winter. Among them, summer is arguably the most dynamic. It not only changes the landscape and clothing styles but also transforms people’s routines, food, and travel habits.
Many foreign visitors assume Korea’s summer would be similar to that of Southeast Asian countries—hot and humid. Interestingly, that’s not always the case. I once recorded the daily temperatures of Guam, which is located in the western Pacific Ocean, for a full year and was surprised to find that its average summer temperature was actually lower than Korea’s. While the difference is small, it challenges the common assumption that tropical regions are always hotter.
However, there’s a noticeable contrast in sunlight intensity. In Guam, the sun is so strong that wearing sunglasses is practically a necessity. In Korea, summer sunshine is much gentler. It's rare to see people walking around cities in sunglasses purely because of the sunlight. This difference in climate has shaped Korea’s unique summer culture in its own way.
1. Summer Escapes: From Mountain Streams to Air-Conditioned Cafés
In the past, escaping the heat in Korea often meant heading to the mountains and cooling off in a stream. Families would pack watermelons or Korean melons (chamoe) in the cold stream water and enjoy a picnic under the trees. The sound of the flowing water and the cool breeze from the valley provided a natural form of air conditioning.
Today, however, this scene is becoming increasingly rare. Concerns over waterborne parasites, E. coli, and environmental contamination have made people more cautious. As a result, many have shifted their summer escapes indoors—into large shopping malls, bookstores, and cafés with strong air conditioning.
It’s common in Korea to see people studying or working in cafés year-round—a group often referred to as “카공족 (ka-gong-jok),” meaning “those who study in cafés.” While this isn’t unique to summer, the number of people seeking out cafés for both comfort and productivity tends to rise during the hot months. Cafés serve not just as places for coffee, but as climate-controlled sanctuaries where people can focus, cool down, and even socialize.
This shift reflects how modern Koreans balance comfort with daily productivity, blending traditional ways of beating the heat with contemporary urban lifestyles.
2. Rainy Days of Summer: Monsoons and Downpours
No discussion of Korean summer is complete without mentioning the monsoon season. Typically occurring from late June to mid-July, this period brings prolonged rainfall that can last several days at a time. Sometimes the rain is steady and constant, and at other times, heavy downpours can flood streets and disrupt travel.
This is quite different from the tropical “squalls” common in places like Guam. While squalls tend to come and go quickly, Korean monsoons can linger, raising humidity and discomfort levels significantly.
The impact of Korea’s summer rain goes beyond inconvenience—it has historically influenced architecture and daily life. In contrast to dry regions like Europe, where solid stone buildings were common, Korea’s frequent rains led to the use of lower, more flexible structures made of wood and earth. Though modern Korean cities are now filled with high-rise concrete buildings, you can still see echoes of these older architectural choices in traditional hanok houses.
3. Cooling Down with Seasonal Foods
Summer in Korea is also defined by its seasonal foods, and one of the most iconic is chamoe, often referred to by foreigners as “Korea Melon.” With its bright yellow skin and white stripes, chamoe is a naturally cooling fruit that helps people beat the heat with its crisp, juicy sweetness.
Koreans almost always eat chamoe with the seeds intact. It’s the norm—not an exception. Only when the fruit is overripe or slightly spoiled would someone remove the seeds. The area around the seeds contains the most moisture and sweetness, and many Koreans agree that removing the seeds greatly diminishes the taste. Unlike Western melons, where seeds are often scooped out, chamoe is typically eaten whole, seeds and all. In fact, chamoe seeds contain digestive enzymes and beneficial nutrients.
In addition to chamoe, other popular Korean summer foods include patbingsu (shaved ice with sweet red beans), naengmyeon (cold buckwheat noodles in chilled broth), and samgyetang (a chicken soup with ginseng, garlic, and glutinous rice). Samgyetang is particularly popular during boknal—the three hottest days of the year—because it’s believed to restore stamina and boost energy.
4. Beaches, Ocean Breezes, and Coastal Escapes
Korea is a peninsula surrounded by water on three sides, making beach trips a quintessential part of summer. From the eastern beaches of Gangneung and Sokcho with their clear, deep waters, to the calmer western coastlines of Incheon, and the picturesque southern seas near Tongyeong and Yeosu, there are endless options for summer fun.
Famous beaches like Haeundae in Busan, Gyeongpo in Gangneung, and Hyeopjae in Jeju Island are magnets for locals and tourists alike. People gather to swim, sunbathe, enjoy seafood, and participate in water sports. In recent years, island-hopping has also become increasingly popular, offering a more secluded and nature-filled alternative to crowded beaches.
Activities such as snorkeling, kayaking, and even jet skiing are available in many coastal areas, making Korea a diverse summer destination.
5. Royal Palaces and Skyscrapers: A City of Contrasts
One thing that surprises many visitors is how seamlessly Korea blends the old with the new. In the heart of Seoul, ancient palaces like Gyeongbokgung, Changdeokgung, and Deoksugung sit gracefully among glass towers, modern museums, and bustling shopping districts.
It’s not uncommon to see tourists in traditional Korean hanbok taking photos in front of centuries-old gates, just steps away from a futuristic subway system or luxury brand store. This contrast is a powerful reminder of how Korea honors its heritage while embracing rapid modernization.
Summer adds another layer of charm to these sites—lush green gardens, lotus-filled ponds, and open palace grounds provide both beauty and tranquility despite the heat.
6. Recommended Summer Experiences for Travelers
If you're planning to visit Korea during the summer, here are a few memorable ways to enjoy the season:
-
Han River Picnic – Rent a mat and enjoy fried chicken or gimbap along the riverbanks with locals. The breeze from the Han River offers a refreshing escape from the city heat.
-
Night Markets – Summer is the season for vibrant night markets. Try street food, shop for crafts, and watch live performances in places like the Bamdokkaebi Night Market in Seoul.
-
Cultural Festivals – Events like the Boryeong Mud Festival, Busan Sea Festival, and Gangneung Danoje provide hands-on cultural experiences and summer fun.
-
Traditional Tea Houses – For a quieter retreat, visit a hanok-style tea house and sip chilled omija (five-flavor berry) tea while listening to cicadas in a serene courtyard.
Conclusion: Korea’s Summer, More Than Just Heat
Korean summer is much more than heat and humidity. It’s a season full of contrasts—ancient traditions and modern lifestyles, mountain streams and rooftop cafés, rainstorms and beach days.
While the season can be intense, it also brings out the richness of Korean life, from flavorful seasonal foods to immersive cultural experiences. For foreign visitors looking to discover something beyond the usual tourist routes, Korea’s summer is both refreshing and unforgettable.
