I still remember my first August in Ansan. I stepped off the bus near Multicultural Street, walked maybe three minutes to my apartment, and by the time I opened the door my shirt was soaked through like I’d gone swimming. The heat didn’t just hit me — it wrapped around me like a wet blanket and refused to let go. Then winter came, and I learned that Korean cold is a completely different animal. Nobody warned me properly. So let me do that for you now, because if you’re living around Ansan’s Multicultural Street — whether you’re a factory worker, student, or just landed — you need to hear this straight.
1. Understand That Korean Humidity Is Its Own Monster
Korean summer isn’t just hot — it’s *jangma* season (장마), the monsoon weeks in late June through July, followed by brutal August humidity that routinely sits above 80 percent. In Ansan, you’re close to the coast and surrounded by industrial zones, so the air feels thick and heavy. What actually works: buy a dehumidifier for your apartment immediately. Not a small cheap one — a real one. Hang-drying laundry indoors during jangma will fail without it, and mold will colonize your walls faster than you think. Run it daily, empty the tank, and thank me later. Also, embrace the Korean convenience store cooling culture — every CU and GS25 is an air-conditioned refuge, and the cheap ice cups plus a pouch drink are a legitimate survival strategy.
2. Layer Smart for Winter, Because Korean Cold Is Dry and Relentless
Ansan winters drop well below freezing, and the wind coming off the Yellow Sea and the industrial complexes makes it feel even worse. The mistake most newcomers make is dressing like they did back home. Koreans have this figured out: thermal underwear (heating innerwear from Uniqlo or Daiso), a proper long padded coat (패딩) that covers your thighs, and heat packs you can buy in bulk at any Daiso for pennies. Your apartment will likely have *ondol* underfloor heating, which is fantastic — but it can make your electricity or gas bill spike hard in January. Budget for it. And never underestimate the wind chill walking from your place to the bus stop at 7 a.m. toward the industrial parks.
3. Master the Ondol, the Fan, and the Cultural Rules Around Both
Two things confuse every foreigner here. First, the ondol: you don’t need to blast it at max. Set it moderately and let the floor warmth radiate. Cranking it wastes money and dries out your skin and throat. Second, the infamous “fan death” myth — many older Koreans genuinely believe leaving an electric fan running overnight in a closed room can kill you. It’s not scientifically true, but if you live with a Korean landlord or roommate, respect the sensitivity and crack a window. In summer, air conditioning is everywhere but often set conservatively in public spaces due to energy-saving norms. Carry a small portable fan. In winter, carry heat packs. These two items will save your sanity more than anything else.
The Brutal Truth
Here’s what nobody tells you gently: Korean buildings are often poorly insulated compared to what you’re used to, especially in the older residential areas around Ansan. That means summer heat seeps in and winter cold bleeds through no matter how good your AC or heater is. Your utility bills in peak July and January can genuinely shock you — sometimes 150,000 to 250,000 won or more depending on your place. There is no magic fix. You either budget for it, move to a newer building (which costs more rent), or suffer. This is the reality of surviving 한국 여름 나기 and Korean winter in a mid-tier housing market. Plan your finances accordingly from day one.
Final Thoughts
Look, surviving the extremes here is absolutely doable — millions of people do it every year. The trick is preparation, not toughness. Get your dehumidifier before jangma hits. Buy your padded coat before the first freeze. Learn how your ondol actually works. And build a little community around Multicultural Street, because having neighbors who’ll lend you a heat pack or split a delivery order makes the hard months way more bearable. You’ve got this. Welcome to Ansan — now go buy a fan and a coat.
