South Korea: when to go?
continental humide climate
South Korea offers a continental climate with four distinct seasons, perfect for discovering its many facets. Spring (April-May) enchants with its flowering cherry blossoms and mild temperatures, while autumn (September-October) captivates with its vibrant colors and dry climate. Summer brings humid heat and monsoons from June to August, a less comfortable period but lively with festivals. Harsh winters transform the country into a snow-covered postcard, ideal for winter sports but demanding in terms of equipment. Seoul and Busan concentrate most of the English-speaking tourism. To fully enjoy the palaces, mountain hikes and cultural discoveries, opt for April-May or September-October when temperatures range between 15-25°C under generally clear skies.
