The cherry blossoms will likely start blooming around March 20th in Jeju, March 24th in Busan, and March 28th in Seoul.
Since the flowers take about a week to fully bloom, the best time to visit the famous cherry blossom streets in Busan will be around April 1st.
That is on average 3-5 days earlier compared to past years, according to the Korean Meteorological Administration.
