Korea Weather & Outfit Guide: What to Wear for Every Season [2026 Edition]

Packing for a trip to Korea is tricky because the country has four distinct seasons with extreme temperature differences.

Summer is as hot as a tropical jungle, and winter is as cold as Russia. If you pack the wrong clothes, you will suffer.

As a local insider at K-Life Lab, I have prepared the ultimate monthly outfit guide so you can blend in with the locals and stay comfortable.
