in South Korea: when to go?
continental humide climate
La Corée du Sud offre un climat continental aux quatre saisons bien marquées, parfait pour découvrir ses multiples facettes. Le printemps (avril-mai) enchante par ses cerisiers en fleurs et ses températures douces, tandis que l'automne (septembre-octobre) séduit avec ses couleurs flamboyantes et son climat sec. L'été apporte chaleur moite et mousson de juin à août, période moins confortable mais vivante avec ses festivals. L'hiver rigoureux transforme le pays en carte postale enneigée, idéal pour les sports d'hiver mais exigeant niveau équipement. Séoul et Busan concentrent l'essentiel du tourisme francophone. Pour profiter pleinement des palais, randonnées en montagne et découvertes culturelles, privilégiez avril-mai ou septembre-octobre quand le mercure oscille entre 15-25°C sous un ciel généralement clément.
