Average Temperature

During August in South Korea, the temperatures soar, with highs typically ranging from 25°C to 30°C (77°F to 86°F) for much of the month. As August progresses, the weather tends to become increasingly warmer and more humid, even reaching the upper 30s Celsius (over 90s Fahrenheit) in Seoul.

Humidity

Coming from a less tropical area of Australia, we found Seoul’s humidity quite noticeable but not unbearable. The most comfortable times to be outdoors were in the morning and late afternoon/evening.

When the heat peaked around midday, we often headed back to our accommodation for a couple of hours to rest and cool off in the air conditioning (and take a nice cold shower). 

If you’re going to find yourself too far from your accommodation during the midday heat, consider planning indoor activities such as visiting cafes, museums, or shopping during this part of the day.

Taking advantage of the air conditioning

Seoul has great air conditioning, with almost every establishment, from stores to cafes, being air conditioned. So, if you’re needing a break from the heat, popping into a convenience store will give you a quick cool down (plus an opportunity to grab a refreshing ice cup and drink pouch!)

While waiting in metro stations might feel a bit hot and stuffy, you can take comfort in knowing that trains are also air conditioned.

When it comes to dining in the middle of the day, I suggest avoiding traditional outdoor Korean barbecues; it’s better to reserve this experience for nighttime when sitting around a hot grill can be more pleasant. I also recommend visiting food markets (like the Gwangjang Market) during the morning or evening as they tend to be crowded, and the heat coming from the stalls makes the humidity feel worse.

Rainy Days

Be prepared for rain during your trip. August marks South Korea’s monsoon season, typically bringing rainfall and thunderstorms on approximately a third of the days. During our 5-day stay, we saw very little sunshine, with most days being cloudy and overcast.

We also experienced sudden, heavy downpours a few times. These showers never really provided relief from the heat, they mostly increased the humidity, making it feel even more muggy.

My advice? Forget about rain jackets (it’s way too humid) and ALWAYS carry an umbrella with you so you’re prepared.

If there’s dangerous weather predicted, the government sends out warnings that you’ll receive if you have a local SIM card. Just make sure to translate these messages if you receive one so you’re informed.

Alright, after hearing about the potentially humid and rainy weather, you might feel a bit apprehensive. But don’t worry! Despite the less-than-perfect weather, we had no regrets. Experiencing another country’s climate and daily life is all part of the adventure, and that’s exactly what we got to do.

Packing Essentials for August in Seoul

Umbrella

As I mentioned earlier, an umbrella is essential. I’d suggest opting for a compact individual umbrella (sharing one doesn’t really work well due to crowded footpaths). An umbrella not only keeps you prepared for rain but is also commonly used for shading from the sun; I noticed many locals doing this.

Hat and Sunglasses

Being out in the open sun, especially with the humidity, isn’t enjoyable. Along with sunscreen, wearing a hat and sunglasses will help protect you from the sun and prevent sunburns.

Cotton or moisture wicking fabrics

When packing your clothes, prioritise cotton, linen, or moisture-wicking fabrics as they’re more suitable for hot and humid weather. This will help you stay cooler in the heat.

Additionally, opt for lighter colours as they reflect heat and play a part in helping you stay cooler.

My preferred outfit during the day consisted of thin leggings, a lightweight t-shirt, and a linen button-up shirt. This not only kept me cool but also protected my arms and legs from the sun, as I tend to sunburn easily.

Dresses and Skirts

I found that flowy dresses and skirts were ideal for the evenings, as I didn’t need to worry about sunburn, and they allowed for airflow and didn’t cling to my body.

Light Sleepwear

Packing lightweight pyjamas will help ensure you can have a more comfortable night’s rest. 

Despite our accommodation having both an air-conditioner and a dehumidifier, there were still nights when I found myself waking up in a layer of sweat.

What are the top indoor attractions in Seoul to beat the August heat?

After enjoying mornings exploring parks, streets, or palaces, head indoors during the hotter parts of the day to experience places like:

Shopping Malls

In Seoul, shopping malls offer more than just ‘shopping’. You’ll find fashion boutiques, electronics outlets, cosmetics stores, cinemas, arcades, and cultural attractions. Notably, the famous Starfield Library which is a popular instagram spot is found inside the COEX Mall. Because the malls are so diverse they’re one of the best places to head to escape both the heat and rain.

Cafes

Seoul’s vibrant cafe culture provides perfect places to relax in the cool comfort of air conditioning. You can indulge in a refreshing iced drink or a warm cup of tea along with a delicious dessert. All while taking in the relaxed atmosphere and watching the vibrant city life bustling around you

Museums

Seoul has many great museums worth exploring. Learn more about Korean history and culture at the National Museum of Korea, or gain insight into the nation’s military history, especially the sacrifices made during the Korean War, at the War Memorial of Korea. If you’re an art enthusiast you’ll also appreciate the Samsung Museum of Art, which showcases a range of traditional and contemporary Korean art.

Indoor Amusement Parks

Lotte World isn’t an average theme park – it’s like Korea’s own Disneyland, but indoors! As the world’s largest indoor theme park, there’s a variety of rides, shows, and attractions catered to visitors of all ages. And it can all be enjoyed away from the sweltering heat of the day.

Final Note: Even though there’s so much to experience in Seoul, remember to not push yourself – especially if you’re not used to the climate. Take some time and rest in the cool and stay hydrated and you’ll have a more enjoyable time.
