Essentials for Seoul in December
Thermal Underwear (tops and bottoms)
Crucial for retaining body heat and forming your essential base layer against the frigid Seoul winter.
Heavy Down Winter Coat
A waterproof and windproof down coat is non-negotiable for staying warm in sub-freezing temperatures and potential snow.
Warm, Waterproof Boots with Good Grip
Essential for navigating potentially icy sidewalks and keeping your feet dry and warm during outdoor exploring.
Wool Socks (several pairs)
To be worn with your boots for extra insulation and to prevent frostbite on your toes.
Warm Hat (covering ears)
A significant amount of body heat is lost through your head, so a warm hat is vital for overall warmth.
Insulated Gloves or Mittens
Protect your hands from the extreme cold, especially when using your phone or exploring outdoor markets.
Thick Scarf
Provides crucial protection for your neck and face from the bitter wind and can be pulled up over your nose.
Lip Balm
The dry winter air in Seoul will quickly chap your lips, making balm an essential everyday item.
Moisturizer (face and body)
Combat the very dry air which can wreak havoc on your skin; a rich moisturizer is a lifesaver.
Portable Power Bank
Cold weather drains phone batteries faster, and you'll be relying on your phone for navigation and photos.
Pro tips
Utilize Indoor Heating Wisely
Many buildings in Seoul use 'ondol' (underfloor heating), which is very comfortable. Dress in layers so you can easily adjust when transitioning from cold outdoors to warm indoors.
Stay Hydrated
Despite the cold, the dry air can still lead to dehydration. Carry a reusable water bottle and drink plenty of fluids.
Plan for Indoor Activities
While there's plenty to do outdoors, factor in cozy cafes, museums, and shopping malls for respite from the cold during the day.
Christmas Lights and Markets
Don't miss the beautiful Christmas decorations and seasonal markets around areas like Myeongdong and Starfield Library – they're magical in the cold, but bundle up extra!
