Complete South Korea Travel Guide 2026

The best time to visit South Korea is spring (March-May) or autumn (September-November) for mild weather, fewer crowds, and vibrant festivals like cherry blossoms or golden foliage, with average highs of 15-25°C and low rainfall.

South Korea's four distinct seasons offer varied appeals: spring bursts with cherry blossoms across Seoul, Jinhae, and Jeju; summer brings beaches and festivals but high humidity; autumn paints temples in red and orange; winter suits skiers and indoor culture seekers with Seoul's festive lights. Avoid peak summer (July-August) monsoons and Golden Week holidays when domestic tourism surges.
