South Korea has a clement climate with four distinct seasons. Its weather is greatly affected by the air currents of the Asian continent, which creates its extreme temperatures during the summer and winter while producing the northeast Asian monsoons at the same time. Thus, winters are typically long, frigid, and dry while summers are short, searing and humid. The weather is nice during spring and autumn, but the seasons are fairly short. In addition, South Korea has an adequate amount of rain each year, receiving more than 100 centimeters of rainfall. The total precipitation varies by year, though, and a severe drought tends to transpire every eight years.
