What to Pack for Seoul Summer: A 3-Year Resident's Honest Guide

What to Pack for Seoul Summer: A 3-Year Resident's Honest Guide

Okay, so you're coming to Seoul in summer? Let me be real with you—it's going to be *hot*. And humid. Like, sticky-clothes-within-five-minutes humid. But don't worry, I've learned what actually works after sweating through three summers here, and I'm going to save you from packing things you'll never use.

The Clothing Basics (Keep It Minimal)

Pack lightweight, loose-fitting clothes. I know this sounds obvious, but seriously—tight clothes feel like torture when it's 35°C (95°F) with 70% humidity. Cotton and linen are your best friends. Bring maybe 5-6 lightweight tops and 2-3 pairs of shorts. You'll be doing laundry frequently anyway (washing machines are everywhere, and jjimjilbang (찜질방) laundry services are cheap—around 3,000-5,000 KRW).

One thing I wish I'd known earlier: bring *one* light cardigan or thin long-sleeve shirt. Indoor air conditioning in Seoul is intense. Coffee shops, offices, and subway cars feel like freezers. I've gotten sick more times from temperature shock than from actual heat.

Footwear That Actually Works

Forget heavy shoes. I rotate between:

• Lightweight sneakers (for walking)
• Flip-flops or slides (for convenience stores, restaurants)
• One pair of breathable shoes for fancier occasions

The streets get slippery when it rains (and it rains *a lot* in summer), so avoid anything with smooth soles. Honestly, I've bought most of my summer shoes at Daiso (다이소)—they're 5,500 KRW for basic sneakers, and it's not worth bringing nice ones when they'll get destroyed anyway.

Sun Protection (Non-Negotiable)

This is where most foreigners mess up. Koreans take sun protection seriously, and you should too. Bring:

• High SPF sunscreen (50+). Korean sunscreen is good and cheap (around 8,000-15,000 KRW at GS25 or CU), but bring what you trust first.
• A lightweight UV-blocking jacket (래쉬가드). Many Korean beachgoers wear these. They're sold everywhere, but GU and Uniqlo have great options (15,000-25,000 KRW).
• A compact umbrella (우산). Summer umbrellas in Seoul are often those cute mini ones—buy one here for 5,000-10,000 KRW when you arrive.

Electronics & Adapters

Bring a universal power adapter—Korea uses 220V and two-pin plugs. You can buy adapters (3,000-8,000 KRW) at GS25 or Daiso, but having one from home saves time.

Pack a portable power bank. Your phone will die from constant map-checking and air conditioning searches. A 20,000mAh power bank costs around 20,000-35,000 KRW here, but bring yours if you have one.

The Secret Weapon: Cooling Gear

This is what makes a difference:

• Cooling towel (ice feeling towel, 아이스 느낌 타올): Around 5,000 KRW at Daiso. Game-changer on the subway.
• Handheld fan (핸드팬): Essential. Grab one for 8,000-15,000 KRW.
• Antiperspirant: Bring good antiperspirant from home—Korean deodorants are more scent-focused than functional.

Medications & Health

Summer in Seoul means:

• Anti-diarrhea medication: Sudden temperature
