South Korea Table of Contents. Part of the East Asian monsoonal region, South Korea has a temperate climate with four distinct seasons. The movement of air masses from the Asian continent exerts greater influence on South Korea's weather than does air movement from the Pacific Ocean.
Koreaâs four seasons have been truly distinctive, in that they each last about three months â a pattern that has been changing somewhat over the past decade or so. Winter (~December to ~end February*) is generally cold and dry, very dry. Although there used to be a lot of snow, thatâs not the case these days.
