South Korea has four very distinct seasons, with winter cold and snow falling between December and March when cold air moves south from Siberia and Manchuria. Average temperatures drop to 0°C (32°F) across the country, with the coastal areas and charming holiday isle of Jeju-do a little warmer. In the capital, Seoul, it can fall to cold as cold as minus 8°C (18 °F) in the depths of winter, so wrapping up warm is a must. It is a great time to try out the country’s world-class skiing and snowboarding resorts, which have among the very best such facilities worldwide.
