Spring is Seoul at its most beautiful. The cherry blossoms that transform Yeouido, the palace grounds, and the Han River parks in early April make Seoul one of the finest cherry blossom cities in Asia, and the combination of warm temperatures, blue skies, and pink blossom against the city’s mountains and modern skyline is the image most associated with Korea internationally.
This guide covers what to expect month by month in Seoul during spring, the best blossom spots, and the events that make March through May genuinely special.
Quick Answer: Seoul in spring: Cherry blossoms peak in early April (exact timing varies by year). Highs of 10 to 18 degrees in March, 16 to 22 degrees in April, 22 to 27 degrees in May.

FAQ
When exactly do cherry blossoms peak in Seoul?
Seoul’s cherry blossoms typically peak between April 2 and April 10, with the exact date varying by about a week based on winter temperatures. In warmer years, blossoms open in late March. The Korea Meteorological Administration releases annual cherry blossom forecasts from February. See the Korea cherry blossom guide.
Is Seoul in spring worth the crowds?
Yes for cherry blossoms, and there are crowd-management strategies that make it very manageable: early morning (before 9 am) at any blossom spot is dramatically quieter. The palaces are most peaceful at opening time 9 amm). Mid-April, after petals have fallen but while fresh green leaves are emerging, has significantly lower crowds with equally beautiful scenery.
Is this guide different from the Korea spring itinerary?
Yes. The Korea spring itinerary is a day-by-day 7-day route that covers multiple cities (Jeju, Busan, Jinhae, Gyeongju, Seoul). This guide covers Seoul across all three spring months, with detailed blossom spots, weekly weather, events, and what to do beyond cherry blossoms.
