Situated in the eastern part of Asia, South Korea has a temperate climate and four distinct seasons. The eastern zone of South Korea is protected by the T'aebaeksan Mountain ranges from experiencing the harsh effects of the monsoons, whereas the western parts experience the winter monsoon fully.

Cheju Island, known also for its volcanic beauty, has milder weather when compared to the western and eastern regions. Located in the south, Cheju sees winter in January, with the lowest temperature recorded at 2.5°C and the highest reaching 25°C during summer in July.

The highest rainfall recorded has been around 100 centimetres. While precipitation may vary from year to year, the country does receive sufficient rainfall. Being heavily influenced by the East Asian monsoons, 1-3 typhoons every year are the norm. These usually occur bang in the middle of summer and bring heavy rainfall.

The coldest month is January, with temperatures in South Korea going down to -5°C, with some cold winds from Siberia thrown in for good measure.

The rainy season, called the changma season locally, is marked by incessant rains. The best months to visit South Korea are between September and November, when the rains would have receded but the gentle nip in the air is still present. The temperature is mild, the weather is beautiful, the air is clean and you can see South Korea in all its natural glory. For mountaineers and those keen on winter sports, December - January is the best time to visit.
