Visiting Korea in August
Visiting Korea in August is as challenging as July, but in a different way. There’s much less rain, more sunshine, and clearer skies, but it’s the hottest month of the year, with equally high humidity levels.
And while the constant rain in July can definitely make travel difficult, the lack of it in August, can make the air feel as heavy as a stone. Prepare to sweat. A LOT!
School age children in Korea have summer vacations in the month of August, so there’s a corresponding major surge in domestic travel around the country at this time.
If you’re planning your visit to Korea in August, and want to go to Jeju Island, Gangwon-do, or any coastal areas, it’s wise to book day tours and hotels as early as possible. Stuff gets fully booked up incredibly fast this month.
Korea in August | Weather
The August weather in Korea is nothing less than exhausting, so it’s important to hydrate well, slather on sunscreen, and take breaks in air conditioning or shaded spots. With a little advance planning, you can still get out there and enjoy all that South Korea has to offer in the summer months.
In August, average daily temperatures in Korea range from a low of 24°C | 74°F to a high of 29°C | 85°F. Doesn’t sound too bad, does it? Until you factor in the humidity, which brings the heat index up to a soul-sucking 35°C | 95°F.
Still… for me, August in Korea is preferable to July. It’s hot, uncomfortable, and muggy, but at least you don’t have to contend with constant rain and depressing grey skies.

Korea in August | Seoul Weather
Seoul in August is steaming, scorching hot, with high humidity and much more sun. This is the hottest month of the year, with a heat index hovering around 35.4°C | 95.7°F. However, average high temperatures actually decrease 2°C | 4°F over the course of the month, from 29°C | 85°F to 27°C | to 81°F.
The Seoul weather in August is technically one of Korea’s wet months, with precipitation expected on around half the days of the month. In my experience though, in Korea in August, rain falls off and on, unless there’s a typhoon. It’s usually not cause for concern (on most days), and really not enough to cool things down much (unfortunately).
*Personal note: I don’t tolerate humidity well at all, and find August in Korea to be quite difficult. It’s been incredibly hot here over the last week, reaching temperatures in the mid-30s and higher.
It does start to cool down a bit in the evenings, so wandering around Seoul after the sun goes down can actually be quite pleasant. However, I do recommend planning some indoor activities for the peak afternoon hours to cope with the insane heat and potential rain.
INDOOR ACTIVITIES | In Korea in August, you sometimes you just need the relief of air conditioning blasting at -500°C. Here’s some ideas.
- Get pampered with a Korean facial at the luxurious Whoo Spa
- See a traditional Korean folk arts performance at the National Gugak Centre
- Spend the day at Starfield Coex Mall, seeing the iconic Starfield Library
- Learn how to fire a gun at the Myeongdong Shooting Range
- Go to the Lotte World Aquarium, Seoul Sky Observatory, and Lotte World Adventure at nearly 50% off with the Songpa L Pass
- Visit one of Korea’s many museums (listing here)
Korea Weather in August | Busan
Busan benefits from its location on the southeastern coast of Korea. It’s slightly cooler than Seoul in August, with average daily temperatures of 24°C | 76.5°F to 28°C | 82°F. The heat index is estimated at 32°C | 90°F, with an average humidity of 81%.
In Busan in August, you can expect little rain and the most hours of sunshine per day. The sea water is also at its warmest at 26.3°C | 79.3°F in August. This is literally the perfect time to chill out on one of the city’s many beaches.
TRAVEL TIP TO SAVE MONEY | Planning to travel from Seoul to Busan via KTX high-speed train? It’s actually CHEAPER to use a Korea Rail Pass than to book separate tickets (111,000 vs 120,000 won).
Beyond that, a Korea Rail Pass gives you UNLIMITED rides on high-speed, regular, AND tourist trains to 600 stations on 80 different routes, for the number of days you choose. Add in the english customer service you get with Klook, and it makes no sense NOT to get one. Click here for more information about the KR Rail Pass.
Korea Weather in August | Gangneung (East Coast)
The Korea weather in August on the East Coast beaches is quite a bit cooler than in the interior. Gangneung in August has average daily temperatures ranging from 20°C | 69°F to 26°C | 78°F, with an average humidity of 83%. The sea temperature is perfect for swimming at 24°C | 75°F.
In my experience, it can feel a bit chilly at night by the sea, if it’s breezy, so be prepared with a light windbreaker or hoodie if you’re prone to feeling cold.
AFFORDABLE PRIVATE TAXI TOUR | This 3 hour private taxi tour of Gangneung area sites provides incredible value at just 20,000 won per car (max 4 people).
Choose between K-WAVE, Coffee City, or Gangneung History Tour to see famous sites like the BTS bus stop, Anmok Beach Coffee Street, Gyeongpo Lake, or Ohjukheon in total comfort. Check availability and select a private taxi tour here.
Korea Weather in August | Jeju Island
Jeju has a temperate humid climate, and in August, the temperatures range from 24°C | 76°F to 30°C | 86°F, with 13 days of rain, totalling around 260-mm of precipitation. August on Jeju is actually the month with the most rain, but it can be a welcome relief from the high humidity and heat index of 36°C | 97°F.
Overall though, if you’re in the mood to swim, August is a wonderful time to visit Jeju Island. The sea water is at its warmest, and there’s plenty of sunshine. Beware though – the UV index is at its highest, and you’ll burn incredibly fast, so slather on that sunscreen and wear a hat.
TIP | Jeju is a surprisingly large island, and public transit can be slow and time-consuming. If you don’t have a ton of time, your best options are to rent a car and drive yourself, or join a group tour of major Jeju Island sites.
- Eastern Jeju Discovery: Horse riding, Seongeup Folk Village, Women Diver Show (Haenyeo Museum on rainy days), Seongsan Sunrise Peak + Manjang Cave
- Western Island Exploration: Hyeopjae Beach, Hallim Park, O’sulloc Green Tea Field, Sanbang Cruise + Cheonjeyeon Waterfall
- Southern Jeju Adventure: Mysterious Road, Hallasan, Alive Museum, Jusangjeolli Lava Cliff, Lonely Rock + Jeongbang falls
- Jeju Island UNESCO Day Tour: UNESCO sites like Manjang Cave, Seongsan Ilchubong Peak, and Hallasan
Korea in August | Typhoons
Typhoon season in South Korea is from July to September. There have been quite a few typhoons over the last few years, but very few of them have been cause for major concern. It can however, mean flash floods, mudslides, and property damage – particularly on the coastal regions of Korea, and on Jeju Island.
If a typhoon should hit while you’re visiting Korea in August, it’s best to stay indoors, shut the windows tight and avoid places where there could be flooding or mudslides (but really, don’t stress too much about it – odds of real danger are low).

Korea in August | What to Wear
To survive Korea’s weather in August, it’s best to wear lightweight clothing that wicks sweat. Breezy linens, technical fabrics, and clothing lines like Uniqlo’s Airism are made specifically to deal with a hot, muggy climate.
You can expect some rain this month, so it’s useful to have waterproof shoes, Crocs type sandals, and quick-dry clothing. I wouldn’t recommend wearing a raincoat during August in Korea. It’s much too hot and muggy and you’d feel like you were suffocating.
Tips for What to Wear in Korea in August
