Jeju Winter Weather: The “Wind Chill” Factor

Unlike Seoul, which is freezing cold, Jeju has milder temperatures. However, Jeju is nicknamed “The Island of Wind.” The wind chill factor makes it feel 5°C colder than the actual temperature.

Does It Snow in Jeju?

The answer depends on where you are:

• City & Coast (Jeju City, Seogwipo): Snow is rare. If it snows, it usually melts quickly. It rains more often than it snows.
• Hallasan Mountain: Yes! The mountain is a snowy wonderland from late November to March. If you plan to hike, you will see deep snow.

What to Wear: The 3-Layer Rule

To survive the Jeju wind, do not just bring one thick coat. Layering is the key.

1. Base Layer: Thermal Underwear (Heattech)

This is non-negotiable. Wear thin thermal tops and leggings under your clothes. They trap body heat effectively without looking bulky.

2. Mid Layer: Fleece or Sweater

Wear a hoodie, fleece jacket, or wool sweater. This layer provides insulation.

3. Outer Layer: Windproof Puffer Jacket

A “Long Padded Jacket” (Long Padding) is the best choice. It covers your legs and blocks the fierce ocean wind. If you don’t have one, a heavy wool coat with a scarf works, but a down jacket is superior.

4. Accessories (Crucial!)

• Scarf & Beanie: Cover your neck and ears. The wind will give you a headache if you don’t.
• Shoes: Comfortable sneakers are fine for the city. If hiking, waterproof hiking boots with crampons are mandatory.

Frequently Asked Questions (FAQ)

Is Jeju colder than Seoul?

No, Seoul is significantly colder (often -10°C). Jeju remains above freezing most of the time. However, due to the humidity and wind, Jeju can feel “damp cold,” which penetrates your bones.

Do I need snow boots for Jeju city?

No. For general sightseeing (cafes, museums, beaches), regular sneakers or leather boots are sufficient. You only need snow boots if you go hiking on Hallasan.

Is it too windy to wear skirts?

Long skirts are popular for photos, but be warned: the wind is strong! If you wear a skirt, ensure you wear thick thermal leggings underneath for warmth and modesty.
