The Weather In Korea In August

August in Korea is peak summer, with temperatures soaring to an average of 28°C to 31°C (82°F to 88°F) and humidity levels to match. The heat can feel intense, but you’ll still find locals and visitors alike making the most of the season, from city streets to coastal escapes.

While August might not be the easiest month for sightseeing, if it’s when you have time to visit, there’s still plenty to enjoy. Plan for early mornings, late evenings, and indoor breaks to beat the heat, and you’ll uncover the vibrant energy that summer in Korea has to offer.

Typhoons in Korea

Typhoons usually head to Korea from the south and can hit during the months of July through September. Generally, by the time the rains and wind get to Seoul, it’s not that strong. If you’ll be on Jeju Island or Busan, you’ll want to watch the weather channels vigilantly to know if any storms are headed this way.

Typhoon storms can bring high winds, flash floods and landslides. Just be aware of the weather while you’re traveling and if a typhoon is headed to Korea, stay indoors.

What To Know About Visiting Korea In August

August is peak summer in Korea, with hot, humid weather and plenty of sunshine once the rainy season ends. Beaches and coastal areas are buzzing with activity, and summer festivals, like the Boryeong Mud Festival, keep the energy high.

Speaking of summer fun, evenings are perfect for outdoor markets and coastal sunsets, with slightly cooler temperatures making late-night adventures more enjoyable. While August can be intense, it’s also one of the liveliest months of the year, full of seasonal charm.

What To Pack and What To Wear

August calls for the lightest, airiest clothing in your wardrobe as temperatures and humidity peak. Bring a fan or cooling towel to beat the heat during the day, and don’t forget sunscreen for all the time you’ll spend outdoors. In the evenings, the heat eases slightly, so you might appreciate a light layer if you’re sitting by the water or enjoying a sunset walk.

The Public Holidays In Korea In August

Liberation Day | August 15: Liberation Day, or directly translated means “Restoration of Light Day”, marks the end of Japanese colonial rule in Korea which was from 1910 until 1945. It celebrates Korea’s independence and freedom.

Did you know there are unofficial holidays in Korea? On August 14, some Koreans celebrate Green Day. Not to be confused with Arbor Day or some other eco-friendly day, Green Day is a day to head out to have a picnic and green bottle soju has really jumped on this one promoting their “green” bottles that are just right for this occasion.

What To Eat In The Summer In Korea

Korean summer delicacies range from cold sweet treats and soups to the hottest of boiling stews. Here’s what to look for when you visit this season.

Samgyetang (삼계탕) is one of the must-have Korean soups in the summer. There will be lines out of doors on the hottest days of summer for this boiling stew made with chicken and ginseng. Samgyetang is healthy and provides the energy we all need in the summer.

Jangeo (장어), grilled eel, is another food known to provide stamina so it’s especially popular in the summer. If you like the Korean bbq experience and seafood, try jangeo, or eel.

Kongguksu (콩국수) is one of my favorite cold Korean soups. Made with buckwheat noodles and a thick soy milk broth, topped with julienned cucumber and sliced tomatoes, it’s filling oh so healthy.

There are a number of other great cold Korean soups like mulnaengmyeon (물냉면), a combination of julienned cucumbers, sliced Korean pear, radish, and a boiled egg or cold boiled beef, spicy mustard and vinegar make the broth quite tangy.

Long, thin buckwheat noodles would traditionally be eaten without cutting symbolizing longevity of life and good health, these days most servers will ask if you’d like the noodles cut as they wield scissors back and forth.

My husband’s favorite option is Pyeongyang naengmyeon (평양냉면), which has been made since the Joseon Dynasty. A North Korean delicacy that is served with buckwheat noodles and a mild cold broth.

Bingsu (빙수) is an icy treat made with shaved ice, glutinous rice cakes, condensed milk and traditionally it has red beans, but these days you can get mango, strawberry, green tea, and all kinds of other bingsu versions.

Fried chicken is good year round of course, but in the summer as the heat rises, it becomes a very popular late night staple in many Korean households. There’s just something about the crisp of Korean chicken, some light beer, and probably sitting back to watch a soccer match.

The August In Korea Flower Guide

Sunflowers (해바라기): Sunflower fields have gained in popularity over the past few years and there are even some great sunflower festivals each year. The biggest thing to look out for though is that if the monsoon rains hit after the sunflowers bloom, it can destroy the fields pretty quickly, so keep an eye on the weather.

Lotus Flowers (연꽃): Blooming throughout the month of July, lotus flowers make mundane ponds come to life in the most elegant of ways. In Korean Buddhist tradition, the different stages of the lotus flower’s growth are often used as metaphors for the stages of enlightenment.
