Boknal: Korea's Three Hottest Days and Samgyetang Season
What and When Is Boknal?
Boknal refers to the three hottest days of the Korean summer, falling on the lunar calendar between mid-July and mid-August. The period is divided into three distinct markers: *Chobok* (the beginning), *Jungbok* (the middle), and *Malbok* (the end). These days typically land about ten days apart during the peak of summer humidity.
While summer weather in Korea is generally hot and muggy, these specific dates mark the absolute zenith of the heatwave season. Historically, farmers needed to sustain their energy through grueling field work in oppressive temperatures, which gave rise to specific dietary traditions designed to help the body cope with the sweltering climate.
The Philosophy of 'Fighting Heat with Heat'
The guiding principle behind Boknal eating habits is *iji-chigi*, which translates to fighting heat with heat. Rather than reaching for iced treats or cold noodles, traditional Korean logic dictates that eating hot, nourishing foods raises internal body temperature to match the outside heat, thereby opening pores, promoting sweat, and preventing the body from feeling chilled and sluggish under air conditioning.
The undisputed food of choice for all three days is *samgyetang*, a whole young chicken stuffed with glutinous rice, garlic, jujube, ginger, and a whole root of ginseng, then simmered for hours in a rich, milky broth. It is served piping hot in a heavy stone bowl that keeps the soup boiling for the duration of your meal.
What You Will See and Experience
If you are in Korea during *Chobok*, *Jungbok*, or *Malbok*, you will not be able to miss the culinary obsession. Walk past any *samgyetang* restaurant around lunchtime or dinner on these dates, and you will see snaking queues stretching down the sidewalk, sometimes waiting for an hour or more.
Restaurants ramp up production weeks in advance, stocking thousands of chickens and extra ginseng. Inside, diners sweat over heavy stoneware bowls, wiping their brows while eating the restorative soup. It is a communal, highly energetic dining scene. If you prefer not to wait in line, many people opt to eat *samgyetang* a day before or after the actual *Boknal* date, or pick up pre-packaged versions from the local supermarket.
Practical Tips for Visitors
Do not be intimidated by the long lines, but do plan accordingly if you want to participate. Arrive at popular specialty restaurants well before peak meal times, or look for neighborhood spots where the queue is manageable. If chicken soup isn't your preference, restaurants serving *dakhanmari* (whole chicken soup) or *chueotang* (loach soup) also see massive crowds on these days as alternative stamina-boosting options.
Be prepared for extreme heat and humidity during these weeks. Stay hydrated, take shade during the peak afternoon hours, and keep in mind that air conditioning in indoor spaces can be very aggressive, making the traditional hot soup surprisingly comforting once you are inside.
Common questions
When are the exact dates for Boknal each year?
The dates change annually because they are calculated using the lunar calendar. They generally fall in mid-July (Chobok), late July to early August (Jungbok), and mid-August (Malbok).
Is samgyetang the only thing people eat on Boknal?
No, though it is the most popular. Some people prefer *naengmyeon* (cold buckwheat noodles) or other stamina foods like eel (*jangeo*) or spicy beef soup (*yukgaejang*), depending on personal taste.
