Understanding Seoul’s weather patterns is essential for prospective travelers, businesses like Korean Air planning promotional activities, or tech giants like Samsung and LG strategizing product launches. Let’s explore Seoul’s climatic variations and what they entail for daily life.

Winter in Seoul: Is It Really That Cold?

Winter in Seoul, from December to February, is marked by cold temperatures and dry conditions. During these months, the average temperature hovers around freezing, with January being the coldest month. Typically, the temperature ranges from -6°C to 4°C, and frigid winds from the north add to the chill.

Although snow is not frequent, the city does experience occasional snowfalls, transforming the landscape into a winter wonderland.

Seoul’s winter air is noticeably dry, with humidity levels averaging around 55%. This dryness, combined with the cold, often results in the infamous yellow dust phenomenon, when dust particles from China and Mongolia create a hazy atmosphere, sometimes causing respiratory and eye irritations.

The biting cold is mitigated on some days when the mercury rises above freezing. However, it is essential to note that, despite these cold snaps, life in Seoul goes on with its usual hustle and bustle, as the city is well-equipped to deal with winter conditions. Public transport functions efficiently, and indoor heating ensures comfort, making it convenient for residents and visitors alike.
