Spring: The Golden Season of Cherry Blossoms
Why Spring Shines
Spring in South Korea, from March to May, is a burst of color. Temperatures hover between 10°C and 20°C (50°F–68°F), making it comfortable for walking and sightseeing.
The country’s most famous cherry blossom spots—Yeouido, Jinhae, and Gyeongju—turn into pink dreamscapes. The mild weather also means fewer mosquitoes and a pleasant breeze.
Visitors often cite the “golden hour” of spring light as perfect for photography. The soft glow enhances iconic landmarks like Gyeongbokgung Palace and N Seoul Tower.
