The rainy season officially ended on July 1 for southern regions including Busan, Ulsan, and Gyeongnam, according to the Korea Meteorological Administration (KMA).
However, central Korea remains under potential influence of a stationary front, meaning the rainy season is not yet officially over for those areas.
Jeju Island saw the earliest end to its rainy season on June 26, marking the quickest conclusion since national weather records began in 1973.
The southern region’s end date this year is the second-earliest on record, following June 30, 1973.
While southern areas are no longer under the influence of the monsoon front, central regions could still receive sporadic rainfall around July 4 and July 6–7, due to a weak stationary front moving south from North Korea.
However, rainfall is expected to be limited as the front is relatively weak and sits within the expanding North Pacific High.
This high-pressure system is pushing the monsoon front northward and is now dominating the Korean Peninsula, bringing persistent heat and tropical nights to much of the country.
In Busan and the broader southern region, hot, humid southwesterly winds combined with strong solar radiation are pushing perceived temperatures above actual readings.
