What to wear in January
Deep winter — prioritize warmth and wind protection. Layers beat one thick coat.
January is the coldest month of the year. Cold winds are common and Seoul's typical low dips to around −6°C, so what matters most isn't how thick you dress but how well you block the wind.
Indoor heating is strong, so the swing is large — a thermal base, a knit, and a windproof outer you can peel off inside beats one heavy coat. Just covering your neck, hands and feet makes the whole day warmer.
Even the daytime high sits near 4°C, so most days never really warm up. Dress for the morning and you are set until evening — there is little to peel off at noon. The drop after sunset is steep, though, so plan around the commute home.

What to wear in January, women and men
For women in January, a long puffer or knee-length heavy coat over a knit dress and fleece-lined leggings works well. For men, a long puffer with a thick knit and lined trousers is the baseline — and for either, a scarf and gloves change how the day feels more than any extra layer.

Frequently asked
Long puffer or coat in January?
For long stretches outdoors, a windproof long puffer is safer. If you're in and out of buildings, a wool coat over a thick knit and thermal base is fine.
How do I handle the indoor–outdoor gap in January?
Layer so you can shed the outer indoors. Keep the base thin and thermal, and adjust thickness with the knit and outer.
Are exposed ankles okay in January?
Not recommended this month — heat escapes fast at the ankles. Wear ankle-covering boots or thick socks.
