Korea's climate is marked by four very distinct seasons. The winters are dry and cold, with snow usually appearing in January. The advent of the cherry blossoms heralds spring—a season that can also be somewhat unpredictable. A brief monsoon season and high temperatures combine to make city life rather humid in the summertime. Autumn is easily the best time of year in Korea, when both the cities and the countryside benefit from clear skies and vibrant fall foliage.
Only 19% of the country is flat enough to be arable, and that land is farmed intensively. In addition, there has been a steady shift away from the farm and into urban areas. Two-thirds of Korea's population now live in its cities.
