Korea in August 2025 | Weather + Best Festivals in Seoul and Beyond

The dramatic monsoon rains typical of Korea in July have passed, but you can still expect blisteringly hot weather in Korea in August.

There is some relief in sight this month though. In 2024, malbok | 말복 (the last of the 3 dog days of summer), falls on August 14th, and travel around South Korea gets progressively more comfortable from this day onwards.

August in Korea is hot, hot, hot… but there’s plenty to do!

In this guide, you’ll learn:

• what the weather is like during August in Korea
• the Seoul weather in August and other major cities and tourist hotspots, including Busan, Jeju, and Gangneung (East Coast)
• the best summer festivals to attend around South Korea in August
• what to wear and the best things to pack for a successful trip to Korea in August

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.

It’s so hot in Korea in August, you might have to resort to an ice bowl.

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!

August is undoubtedly the best month of summer to head to one of the many beaches around Korea for some relief, splash around at a huge water park, or relax poolside at a luxury hotel.

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 Weather in August Quick Guide

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.

Camping with the family near mountain streams is very popular in Korea in August.

In August, average daily temperatures around Korea range from a low of 20°C | 69°F to a high of 30°C | 86°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).

Starfield Library is a good place to spend an afternoon.

*Personal note August 2024: I don’t tolerate humidity well at all, and find August in Korea to be quite difficult. We had a long rainy season that kept things relatively comfortable, but since it ended, it’s been incredibly humid here, 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.

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.

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.

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.

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.

Maemiseong Fortress on Geoje Island was built by hand, by one man – to protect the land from future typhoons.

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.

Dripping sweat at Yeonmisan Nature Art Park in Gongju, despite wearing Airism clothing.

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.
