South Korea experiences extremes in terms of its climate. The winter months see freezing temperatures and great ski conditions - South Korea will actually be hosting the 2018 Winter Olympics in Pyeongchang. Spring sees a rise in temperatures and beautiful blossom across the country, perfect for the snap-happy amongst you. From June to September the heat is on, with high humidity and heavy rain in July in particular. Autumn however is a great time to visit with the natural areas of South Korea ablaze with colour.
