I remember my first August in Seomyeon vividly. I had just walked out of exit 7 towards the Lotte Department Store, wearing what I thought was a breathable linen shirt. Within three minutes, that shirt was glued to my back, my glasses were fogging up, and I was questioning every life choice that led me to a city where the air feels like a wet, hot blanket. Coming from a dry climate, I thought I knew heat and cold. I was wrong. Busan doesn’t do weather in half-measures; it swings between a swampy sauna and a wind tunnel that cuts through your bones. If you are new to Seomyeon, or planning to move here, here is how you actually survive the extremes without losing your mind.
1. The Summer Survival Kit: Beyond Just AC
Seomyeon is a concrete jungle, and during the “Jangma” (rainy season) and peak summer, that concrete radiates heat long after the sun goes down. You cannot rely solely on your apartment AC because the moment you step outside, the humidity hits you like a brick wall. Your first purchase needs to be a high-quality dehumidifier for your apartment. If you don’t run one, you will wake up to condensation on your windows and, eventually, mold on your walls—a nightmare that will cost you your deposit when you leave. For your body, invest in cooling towels or a portable neck fan. When walking from Seomyeon Station to the food street, these little devices are the difference between arriving fresh and arriving looking like you just ran a marathon.
2. The Winter Struggle: Layers, Layers, Layers
Korean winters in Busan are deceptive. It looks sunny and beautiful from your window, but the wind coming off the ocean creates a “wind chill” effect that makes 0°C feel like -10°C. The biggest mistake foreigners make is relying on one heavy coat. The secret to surviving winter here is the “Onion Strategy.” You need a thermal base layer (Heattech is your best friend), a mid-layer like a fleece or sweater, and a windproof outer shell. This is crucial because Korean interiors—subways, cafes, and offices—are heated to tropical temperatures. You will be freezing on the street and sweating in the cafe. Being able to peel off layers is essential for your sanity.
3. Ondol vs. The Dry Air Battle
In Seomyeon, most apartments use “Ondol,” which is underfloor heating. It is fantastic because it warms the floor, but it also sucks every drop of moisture out of the air. Combined with the dry winter wind, you will wake up with a sore throat and cracked skin if you aren’t prepared. You need a humidifier for the winter months. Conversely, in the summer, you need to master the art of the “aircon battle.” Koreans often prefer fans over AC, or they set the AC to a specific “comfort” temperature. Learn to communicate about the temperature in your workplace or with roommates, or you will spend your first year either shivering or sweating in silence.

The Brutal Truth
The harsh reality about living in Korea, specifically in a busy hub like Seomyeon, is that the concept of “personal space” regarding temperature does not exist in the same way it does in the West. In the summer, you will be crammed into a subway car during rush hour where the AC is weak and the body heat is intense. In the winter, you might sit in a restaurant where the door is left open because the owner is hot, while you are freezing in your seat. You have to accept that you cannot control the environment. You can only control your preparation. If you are someone who needs constant climate control to be comfortable, you will be perpetually miserable. You have to learn to adapt your body and your gear to the environment, not the other way around.
Conclusion
Living in Seomyeon is an adventure, and the weather is just part of the package deal. It’s intense, sure, but it also gives you a reason to enjoy the cozy cafes in winter and the breezy beach walks in late autumn. Don’t let the weather keep you inside. Gear up, layer up, and get out there. You’ll survive the seasons, and eventually, you’ll even start to brag about enduring the Busan heat and cold. Stay strong, fellow expats.
